Rolex WIKI Page - All the basics

[Sylhab03]

Very useful thanks

 

[skx]

By reading I understand that a rolex dd can have chinese, asian clone, super clone, eta, and some rolex rep movement.
If the chinese is not reliable, the superclone has not much experience, the eta is not new, the rolex is not the first choise of many....
Then I should choose the asian clone because it is reliable, new, high beat, easy to service and easy to repair and find parts.

Could somebody confirm this please.

So that should be a A2836.
This is for my first rep, puretime has a dd gray striped dial noob factury. Is this the better choise?

 

[d4m.test]

Will you add the new movements? Like the SH3135?

 

[d4m.test]

this is a great reference!
Thanks for all the hard work.

 

[d4m.test]

Great overview. Perfect for a noob like me.

MOVEMENTS - Basic Concepts

~ 21j (DG2813 / DG4813 / DG2812 / DG4803) ~
21j Movement Tech Forum
Ofrei Chinese Movements List

Asian 21j Disassembly Video in HD

The most basic of all movements to be found in Rolex Replicas. This is a cheap, workhorse movement. Works at low beat (21,600 bph) as opposed to high beat movements (2836 etc). Can be replaced for as little as $10-30 USD.

The DG4813 is a variation that runs at high beat. This is not a direct drop in replacement due to the canon pinion height and would need to be modified to work with most Rolex replicas. These were available for a short period of time in some Rolex replicas but seem to have been out of production for a while. You can still purchase a DG4813 from regular supply companies (CousinsUK/Ofrei) but would need to do a canon pinion swap with a DG2813 with high canon pins.

New project samples ready! High beat 28800 21j Asian

The DG3804 is a true functioning GMT movement working at low beat and is accurate for hand stack and very close to the correct beat rate for older GMT movement Rolex watches.

This is the variation most likely seen in the DayDate replicas and is, as above, low beat but with day as well as date function.

~ Asian Clone (2836 / 2824) ~
2836/2824 Tech Section

Asian 2824 Clone

High beat movement based on the ETA 2824. Reliable high beat movement.

Asian 2836 Clone

High beat movement based on the ETA 2836 with day and date functions. Primary choice for most Rolex replicas.

ETA 2836-2 vs Clone - how to tell "Swiss" from "Asian"

Asian "Superclone" (2836 / 2824)

Not a lot of discussion has been had on these new 'superclone' movements. In understanding the differences between Clone/Superclone/ETA movements you should start here ("Swiss" ETA / Asian Superclones / Asian Clones – What’s the best choice?). In that thread you will find links to teardowns done on this vs Swiss movements. I will quote here from the conclusions of the teardown threads.



~ A3135 Clone ~
3135/3131 Tech Section

*Picture credit PureTimeWatches*

This is a clone movement that has been 'dressed' up to look like a Rolex 3135 movement. It is considered to be less reliable than the standard clone movement as it has been modified beyond the original specifications. The screw holding the rotor in place is notoriously weak. Please read this thread for more information (3135 Gen vs Rep)

~ A3156 Clone ~

The same stipulations apply to the A3156 Clone movement as do the A3135 movement. This is a clone ETA2836 that has been made to emulate the 3156 movement found in the Rolex Day-Date watches.

3156 clone questions

~ A3131 Clone ~

As above this is the non-date version of the tarted up clone movements. You can find this movement in the Explorer I and Milgauss replicas.

~ A3187 Clone ~

This is the GMT movement that you will find in some of the new Explorer II 42mm 216570 replicas. I have not seen this movement in any other replicas so far.

~ SA3135 Clone ~

*Picture credit PureTimeWatches*

*Picture credit 1234_Cool_Uncle*

This SA3135 movement was originally described as being a proper clone of the 3135 Rolex movement. And in some ways it is. The V1 of this movement is notorious for having a weak stem (All about SA3135 movement). This has possibly been remedied in V2. There is also a second version out there which is slightly different. Both are reported to take gen dial, hands, and datewheels but information is light on the ground. There is also another version that TC reported on being in production which due to privacy reasons he has decided to withhold the publishing of pictures.

There is more information / discussion on the SA3135 in this thread

Please also see Warrcrafts thread on
Rolex SA3135 Movement Observations.

Some great comparison photos between the SA3135 and the genuine Rolex 3135 movement by 1234_cool_uncle can be found in this thread
Compare with the 3135s

~ A7750 (Seconds at 6 / Second at 9) ~
7750/7753 Tech Section

*Picture credit PureTimeWatches*

This movement is found in the Daytona replicas currently available. It comes in two variations. With running seconds at 9 o'clock and running seconds at 6 o'clock. The seconds at 6 movement is notorious for being unreliable due to the additional gearing needed to transfer the running seconds from 9 to 6. There are new versions out that have 29 jewels and an increase in stability.

For information on the upgraded version with 29j movement please read this awesome thread by 14060 or 16610?
The "New and Improved" Seconds-at-6 Movement Explained

The seconds at 9 movement is the native configuration of the 7750 movement and doesn't represent a significant danger of failure. These are present in some replicas representing the Daytona from the period when it used the Zenith El Primero movement.

~ Venus 75 / Lemania / ST-19 ~
Seagull Tech Section

*Picture credit PureTimeWatches*

This is a bi-compax movement (meaning just two subdials, 7750 has 3). This often means that watches with this movement have a false register that follows the hour hand around the dial. You will find this movement in the vintage Daytona replicas. It is a sturdy and reliable movement with no serious issues. Modifications can be done on the faux subdial to freeze it in place.

PRICES - How much should I pay?​

The bigger question is how much do you have to spend. You can start in the sub $100 range and go all the way up to over $1000 for franken or rare pieces. Here's a rough guide of what you can expect for your money.

~ $1-$99 USD ~​

Most sub $100 USD watches are going to be either 21j models or Quartz. These tend to have poor construction, inaccuracies and are at the low end of quality materials. They will generally have mineral glass crystals rather than sapphire. As a result of the lower cost movements in these watches they will tend to be low beat, and generally inaccurate to the genuine Rolex beat rate of 28,800 bph.

If it is a model with complications; Daytona with chronograph, Yachtmaster II with timer etc. Then these are more than likely faux complications. This means that they will not function as per the genuine watch. For example the Daytona which uses the 21j movement (also called Asian Automatic) has sub-dials that will represent the day/date/week and can be moved by the pushers. But it is not a chronograph. See pictures below.

*Picture credit Timeshops.net*​

Also in this price range are low end replicas of vintage models. Because the 21j movement is close in beat rate to the original movements they are preferred. It is also a good base for customising or 'vintaging' an older Rolex model.

• 21j or Quartz movement
• Mineral Glass
• Innacurate construction
• Vintage base watches
• Faux complications

~ $100-$200 ~​

Now we are entering the region of good replicas. The higher end 21j models will tail off in this price range and you enter clone movement territory. Once you hit the $150+ range you are almost definitely going to be receiving a watch fitted with a clone movement. Either a 2824 or a 2836 variation. It is unlikely that you will find an A7750 movement in this price range without some sort of dealer discount. In combination with better movements you will likely find better construction, sapphire crystal. In addition to this they will generally be more accurate than the cheaper models.

• High end 21j / Swiss Quartz
• Clone movements
• High beat movements
• Sapphire crystals
• Better and more accurate construction
• Decent lume (but generally not superlume)

*Picture credit Timeshops.net*

~ $200-$350 ~​

This is the price range where it starts to get a bit more interesting. How much more watch are you getting for that extra $250 over the sub $99 range? Well at the lower end of this price range you are getting watches with clone movements, sapphire crystals, much better accuracy to genuine watches and generally better construction. Creeping into this price range is also the watches with claimed 'super-lume'.

You will also find the A7750 / Lemania movement watches in this price range with working chronograph functions. At the higher range you are getting Swiss (or Superclone) movements and also some of the A3135 movements.

• Clone / Swiss Movements
• A7750 / Lemania Movements
• Working Chronographs
• A3135 Movements
• Sapphire crystals
• More accurate case set
• Superlume

For example, here is the top end of the budget at $348. This Seadweller 16600 comes both superlumed and with the A3135 movement as well as the usual upgrades of sapphire crystal and a much better case construction.

*Picture credit PureTimeWatches*

~ $350-$500 ~​

So now we are getting into the realms of expensive replicas. This is where you find the likes of A3135/SA3135 movements, NOS SW220 and ETA movements bought in by smaller specialised dealers. You start to see the offerings from BKLM entering the picture at around the $370 mark for his Explorer II's up towards the modified ceramic noobfactory submariners at around $420.

All of the watches in this price range start to boast the same level of quality. Be it accuracy of construction to the genuine watches, or improved movements (guaranteed Swiss from BKLM) to upgraded QC control. This really is the higher end of unmodified Rolex replicas and the start of either modified or "Boutique" dealer replica offerings.

~ $500 upwards! ~​

From here on the sky is the limit. You stop getting standard dealer offerings at this level and start entering the world of custom work, franken pieces, rare and discontinued pieces and the small offerings from "Boutique" dealers (TC, Sean, and BKLM).

Some frequently asked questions

How do I tell Rolex crowns apart?

Please visit this great thread for lots more information on the subject:

Rolex Crowns - How do you tell which is which? by justlounging

How do I use a GMT watch?

"Greenwich Mean Time (GMT) is a time system originally referring to mean solar time at the Royal Observatory in Greenwich, London, which later became adopted as a global time standard."

Greenwich Mean Time
From Wikipedia, the free encyclopedia

Having a GMT hand on a watch DOES NOT mean that you have to leave it indicating the time in the UK. It just means that it has the ability to track a second time zone should you wish. The fourth hand on the Explorer II and GMT replicas functions as an hour hand that rotates round the dial once every 24 hours. So many people make using and setting a GMT hand a complicated procedure when it really isn't.

As a general note for ALL automatic watches: do NOT change the date or GMT hand between 10pm and 2am. This is when the date change mechanism is starting to engage to automatically change the date. Adjusting the date or GMT hand during this time risks damaging the date change mechanism.

On a GMT movement you have 4 positions to the crown.

1: Screwed on to the crown tube
2: Unwind crown until free from tube - winding position
3: Pull out 1 stop - date and GMT hand setting position
4: Pull out 2 stop - time setting position

In position 2 winding clockwise will wind the mainspring of the watch. Counter-clockwise does nothing.

In position 3 winding clockwise will advance the date, winding counter-clockwise will turn the GMT hand.

In position 4 winding clockwise will turn the hands backwards, winding counter-clockwise will advance the time.

You can use the 24 hour hand in two ways. Firstly you can set it to your home time zone. Whilst like this you can read the 24 hour clock from the bezel. The GMT hand will point to the 24 hour time. So if it says '10' it's 10am. If it points to '16' it is 4pm.

Secondly you can move the GMT forward or backwards in relation to your own timezone. This way you can track any other time zone in the world either +12 hours or -12 hours.

Thanks to gioarmani7428 for this useful information:

Not many people know that on a GMT bezel, the wearer can use the 24-hour dial for approximate navigation anywhere between the Tropic of Cancer and the Arctic Polar Circle. But, both the 12 and the 24 hour hand must be synchronized to display local time.

Method 1: When laid horizontally, the dial will head North if the 24 hour hand is pointed towards the sun.

Method 2: If the 12 hour hand is pointed at the sun, the 24 hour hand will point North.

The margin of error directly depends on the difference between local official time and actual local solar time, which is why you have to be between the Tropic of Cancer & the Arctic Polar Circle. But one doesn't need to get too much in the technical details for approximate North, East, South, West navigation.

Little known fact about GMT watches by gioarmani7428

What is the difference between a 'Chronometer' and a 'Chronograph'?

This is a very common question since people often confuse the two. While their names may sound similar, these terms have very little in common.

Chronometer is the term used to describe a highly-precise timepiece which, after rigorous testing, has received an official timing certificate from the official Swiss timing bureau Controle Officiel Suisse des Chronometres (COSC). Thus, it is a rating or accolade given for the watch's accuracy.

A chronograph on the other hand is a timepiece that, in addition to the normal time telling functions, also performs a seperate time measuring function such as a stop watch -- with a seperate seconds hand which can be started, stopped and reset to zero, via push-buttons on the side of the case. Please do not confuse 'chronographs' with 'complications' (which are described below). While all chronographs can be considered complications, not all complications are in fact chronographs.

What do 'complications' mean when referring to a wristwatch?

A complication is described as any additional function the wristwatch performs beyond basic time telling (i.e. hour, minute and second). A common example of wristwatch complications are calendar models which display the day/date. Additional complications include chronograph models, whereas the watch performs like a basic "stop watch" (as described above). Other complications worth mentioning are: second time zone, moonphase and alarms.

What does the "T" designation at the bottom of the dial mean?

This refers to the chemical used on the hands and hour markers, which causes them to illuminate. Around 1950, watchmakers started using Tritium as their luminous material, and began indicating the amount of that radioactive material with a designation at the bottom of the dial (i.e. T SWISS T or SWISS T < 25). Around 1998, watchmakers changed the designation to read SWISS or SWISS MADE, when they replaced the Tritium with LumiNova (an organic, non-radioactive chemical), as their source of luminescence.

T SWISS MADE T indicates that the radioactive material Tritium is present on the wristwatch. The amount of radioactive material emitted is limited to a maximum of 25 milliCurie.

SWISS T < 25 more specifically indicates that the wristwatch emits an amount of Tritium that is less than the 25 milliCurie limit.

SWISS T 25 indicates that the wristwatch emits the maximum allowable amount of Tritium (i.e. a full 25 milliCurie).

SWISS (or) SWISS MADE on wristwatches produced after (around) 1998, indicates the presence of LumiNova as the luminous material. (Please Note: "SWISS" or "SWISS MADE" was also the indication on wristwatches produced prior to the 1950s, when Radium was used as the luminous material. However, at that time "SWISS" or "SWISS MADE" simply indicated that the watch was, in fact, made in Switzerland.

Why is the Day-Date sometimes called a "President"?

Actually, Rolex has never referred to the Day-Date watch as a "President". However, the BRACELET we are used to seeing on the Day-Date is known as a President, since one was fitted to President Dwight D. Eisenhower's watch during a service overhaul in 1956 -- the same year the Day-Date was first introduced.

And as a little known trivia fact, President Eisenhower's watch wasn't even a Day-Date... it was an 18kt Datejust given to him by Rolex in 1946 to celebrate the WWII victory -- and Winston Churchill was also given one at the same time.

What kind of Stainless Steel does Rolex use in their watch cases?

SS 316L vs. 316F vs. 904L- A technical study *Award winning post*

While most high-end watch companies utilize 1.4435 (or 316L) Stainless Steel, Rolex uses 1.4439 (or 904L) Stainless Steel. While they both have the same grade of hardness, 904L has a slighytly higher nickel discharge, and thus a slightly higher resistance to corrosion. 904L is mainly used in industry applications handling chlorides, sulfer dioxide gas or other toxic materials. While this may sound like overkill for use with wristwatches, it's just another exaple of over'engineering on the part of Rolex where only the best will do.

What is Rolesor?

This is a Rolex term to indicate the case/bracelet configuration of Stainless Steel and Gold.

What is Rolesium?

This is a Rolex term to indicate the case/bracelet configuration of Stainless Steel and Platinum.

Is there anything I can do to make my watch run a few seconds fast/slow each day?

If your watch is off a few seconds per day (fast or slow) you can regulate it depending on the position you leave the watch at night when you're not wearing it, as follows:

By leaving the watch's dial (or face) up can cause it to gain (or run fast) up to a few seconds per day. On the other hand, by leaving the watch's dial (or face) down can cause it to lose (or run slow) upto a few seconds per day.

What is an SEL?

Solid End Links (or SEL) refers to the final link on select modern Rolex bracelets. On these SEL bracelets, the final link is made from a solid piece of metal where the bracelet attaches to the watch's case (or head). This new design makes for a stronger bracelet and a cleaner look. On older bracelets, they utilized a hollow end piece to attach the bracelet to the watch's case

What is a "Nipple Dial"?

This is a variation of the regular dial markers seen on vintage Submariners and GMTs. See the picture below for reference.

What is a "Serti Dial"?

The French (or Swiss) word 'Serti' translates as 'inset'. A Diamond or other gem-set dial is thus described in the Rolex catalogue as 'Cadran Serti', meaning, inset dial.

What Do The Numbers Mean... Model numbers explained

Rolex model numbers currently four, five or six digits long. The first two or three describes the type of watch. If the watch has five digits, the second from the last describes (some exceptions) the type of bezel and the last describes the material that the watch is made from.

Typically the reference number only changes when major changes are introduced to the watch. If only minor changes are made a "1" is added to the beginning of the old reference. So in the early 2000s when the 14270 Explorer was remodeled only slightly it became the 114270. Major changes such as the introduction of a larger case or major cosmetic differences will result in a totally new reference number all together.
