Can some one tell me the difference in movements?

[jaydg66]

Can someone help me out and tell me the difference between the movements?
So far I have notice Asia Valjoux 7750, Swiss Eta 2671-2, Swiss Eta 2836-2, Asia 21J and I know there are more out there that I have seen but I am getting lost on all the different movements. Maybe I have missed the area were you guys have talked about the different movements and if so please let me know were or if not can someone explain to me. I would like to buy a watch, so far I been looking at the Bell&Ross and Panerai and I notice that they have different movements. I been looking at Josh's web site and he looks like he has some great stuff. So back to my question, I take it some are better movements then others and are easier to work on?

Hi,

Your question is pretty broad. If you click on the link in my signature it will take you to a spreadsheet where I describe the ETA movements, their sizes, speed and complications / layout. Maybe it will help you.

ok that did help me out a little, but I guess I am such a rookie and I am still learning is there a movement that is better then other movements? Not sure if that make since or not. I am only asking since a couple of watches that I have been looking at seems to only come with Asia 7750 and Asia 21J. Is one better then the other?

HI,

The asian 21J movement is one of the cheapest & unreliable movements made. This is why most watches that come with this movement are so cheap. The asian 7750 if (28,800bph) is a pretty reliable movement and most commonly associated with Chronograph watches like the Rolex Daytona or IWC 3717, Hublot Big Bang, Breitling Navitimer and Evolution.

An ETA 2824-2 and 2836-2 are nice movements to have in a watch. The 2836 is commonly found in a watch with day and date function and the 2824 most commonly found in watches with a date function.

The 7750 movement is capable of the day/date complication as well.

Swiss versions of the 7750 are pretty expensive and thus takes the traditional replica chronograph watch cost well above $500.00 and usually closely approaching the $800-$1000 mark.

I have all of these movements in one or more watches and would recommend all except the 21J movement for long term use. If you are planning to purchase a Breitling Steel Fish Super Ocean I would not purchase it with the 21J movement because I see too many threads where people have problems with this movement in this watch.

I hope that this helps you out.

d4me did a pretty good job explaining it already, i dont know what this will add but i'm bored:

asian movements < swiss movements

it's that simple.

asian 7750 < swiss 7750

all quartz are pretty much the same.

further investigation:

asian 21j: most typical movement found in a 100$ automatic watch. I've noticed so far in the years of collecting that i've not had problems with it, but then again, i've only got one watch with that mvoement in it. It is a basic mass manufactured movement. Problem is if you have issues with it and need replacement parts, most local watchsmiths will have difficulty fixing or replacing parts. Swiss is more of a standard so parts/repair is much more available. the BEAT RATE on asian21j is SLOWER (the second hands sweep is more jittery than the swiss counterpart). btw ASIAN 21J is not the miyota japanese movement.

swiss ETA's: 2824, 2982, etc, all by the company ETA which is owned by the swatch company (i think), they provide movements to many recognizable companies including omega, tag, panerai, etc. You will pay the extra price for a better manufactured movement with a better sweep rate (smoother seconds movement) and more available repair or service options when that time comes. the different 2824, 2982, differ mainly in function or location of gears or second hands. ie the 2571 is a swiss mvoement for ladies watches - same beat rate, just everything... smaller.

note that all mechanical watches will need service at one point or another. So going swiss is the easier longterm route, though higher in cost.

i've also noticed a higher quality associated with buying reps with swiss movements; IE: the asian 21j cartier santos galbee i bought was lower in quality (case, bracelt, etc) than the higher priced santos with swiss mvoement. It's not absolutely true, just a trend i noticed. many will stand to note that there are lots of exceptions. that's cuz we have great dealers sourcing us awesome deals

the 7750 is an ETA movement with chronograph functions (stop watch function), so it'll cost more because of the more gears that are shoved in there. It's a much more delicate system so servicing this movement will cost 2 -3 x than regular watch mvoement.

there is an asian version we've so called A7750 (asian 7750). Basically the same functions, but because parts milled have a lower quality, and because the complexity of the movement, people get scared of it breaking down (though i've heard the newer hibeat ones are quite reliable and better made).

so if you look at the costs this way:

asian21j rolex = 100
swiss mvmnt rolex = 200
asian7750 rolex = 200
swiss7750 rolex = 500

costs roughly double from teh standard movement to 7750's. they also double from the asian mvoement to the swiss counterpart.

another movement we havent really talked about are the manual winding ones found in chrono's and pannies. i guess we can save that for another day if you like.
