Finally, I got this revolutionary replica handy now, and have a chance to do closer look on this piece: IWC Portuguese IW503502. Revolutionary? why? because the calendar really working on this version. Date, Day, and Month are working on this YL factory made. YL factory well known as the maker of the cheaper version of IWC Portuguese 5007 series. Unfortunately ZF leading the way on that version with some correction. YL factory claimed that this movement and detail decoration is better compared to their previous 5007 series.

First time on my hand, I really impressed with the build, very solid. And when I look at the caseback, there are clearly improves from the previous Portuguese 5007 movement series, you will see by keep reading this topic.


There are 2 major perfections on this model, from my point of view:

1) Real power reserve, even only approx 48 hours (genuine is 7 days), but this is quite excellent with the power reserve indicator pointing on the right reserve left.

2) Real working calendar. This is the first time after all for this model. However, please do not expect that it will be the real annual calendar. You need to accept the fact that:
  • The date will always end on 31
  • The month will always move after 31
  • There is no setting position to set the month manually, you need to turn the date wheel to get to the current month. Only date and day that have an independent crown manual setting. (you can see on video)
Well, let's take a look how good this replica is, away from the features.


HOW THE CALENDAR WORKS?
This is the most interesting parts on this replica since YL made a good breakthrough this year by making this perfect model working well. I provide you with the video how to set the day, date, and month on this model



WATCH FACE

35057445573_1aaa709348_c.jpg


You won’t probably find easy to spot the difference on the dial. I think YL made this part properly with a good detail. The only noticeable difference is the font size of Month, Day, and Date. To make it more clear, I provide another picture as below:

35734899591_3234693d1f_c.jpg


The font on replica is too short
The font on replica is too thick


The date position is not centre (maybe other units have better position on this, I need to make sure)

I don't think font style is the issue on this, only the size has some flaws as explain on above points.


DIAL DETAILS

35734939301_2326ea46b7_c.jpg


Except for the date, month and day font. I can see perfection on other dial parts, such as:

The blue sunburst effect is very nice. I don’t think the dial colour is off as some guys told me. It is just nice

The subdial line is very neat. You won’t probably able to see that line if you are not looking at it closely. Bottom line, those subdial details is perfect.

Hour marker is nicely replicated, I didn’t see major flaws on that part

No issue on logo’s font and size, all good from what I can see

Overall on the dial parts, YL is very detail on this part, except the date, month, and day font size.



CASE DETAILS

35826003126_d7dc21d5a7_c.jpg


I like the way YL doing brushing on the outer side case, even some people said it needs to be softer, but I love this. The brushed and polished combination on the case and lug are very nice.

I don’t think crystal and thickness have a major issue on this, since YL use A23j manual wind movement, it won’t be too thick compare to 7750 movements.

Crown is very detail, there is no sharp feeling when u start to turn it. Crown engraving is nicely done!

Only 1 single minor flaws on the crown thickness, it shouldn’t be that thick, need to be a little bit thinner. But I don’t think that is something that you should complain.


MOVEMENT COMPARE

35057435303_efa1784ebf_c.jpg


Movement of this model on genuine is Calibre 52850 IWC annual calendar 7 days power reserves. YL still use A23J manual wind to replica this calibre. I can see some correction compare to the movement made by YL on Portuguese 5007 series before, but:

Black gear is quite annoying to see, it should be there on the replica. But YL uses gold gear instead of black.

It should be SWISS MADE instead of SWISS TECH. Exactly the same mistakes as 5007 series made by YL.


MOVEMENT DETAILS


Besides those differences, I think YL also make some perfection on how the decoration was done, and how the movement finished. It is quite detailed and well builds as you can see on below pictures:

This movement has all the same function of the genuine, including the way, are synchronised with the genuine: PR display, month, week; compared to the movement of 5001/5007 with additional week and month functions. But we do not know these two additional Day / Year functions took three years for development, it started the same time research and development with the 7 days (5001/5007) but late release for another 2 years, you can imagine the difficulty of movement development + research time it took. Other main important factor also related to the cost and watch technology. YL factory Portuguese annual calendar series IW503502 movement thickness and size matches the genuine, compared to the 7 days movement with slightly thicker than the genuine, it is because the movement manufacturers have made some improvements, the automatic chains made to the real version, professionally called DD template; therefore the manufacturer of the 7 days movement wants a better effect on the deck, therefore make it thicker, and the rear three-dimensional effect is not so strong! This new piece from YL factory represents a simple design and neat dial, suitable for any occasion to wear, equipped with a new movement, this watch can be described as a new milestone in the history of IWC REP.

All engravings on the rotor are neat. The movement textures also very detail from what I can see. Gold engraves are nicely done, except the “Swiss Tech” flaw, and the gold gear that should be black as genuine it is.


STRAP & BUCKLE

35734912051_42ce0ac7b5_c.jpg


Nothing to complain. As always replica using crocodile embossed, but I think still quite nice and acceptable as a strap. The curvy lug is there as genuine. The buckle? very details, no complain!




TEAR DOWN + Reviews

Introduction:


While everyone is still in the Portuguese and Pilot series, in the REP world many have long been tempted to keep the old mind, eager to see a high value of the new model to replace the Portuguese 5001/5007 and the Portuguese 3714. After YL Factory 3 years of movement research and development, continue to overcome difficulties, manage to produce this high-value watch. Today to showcase the 2017 YL factory latest masterpiece Portugal Calendar series model IW503502 and detailed evaluation. This 5035 has a fully functional calendar, can be described as a re-engraved Portuguese series watch, the following is the pictures after the complete dismantling of the watch.

35479017140_6c7b990391_c.jpg


Night blue dial, calendar display design simple and neat, with three independent semi-circular windows, respectively, display the month, date and week, between 11 Index to 1 Index. Small three-pin design, 3 o'clock power reserve slot display, 9 o'clock set a small second and Arabic numerals. The layout is clean and the reading date is easy.

35867026335_24a7bd872e_c.jpg

35735188871_832156b32e_c.jpg


Case thickness is more moderate, in the 44mm large dial does not seem too thin and not too thick, side of the brushed case has always been the style of Portuguese series, YL factory drawing is very delicate, personal also like drawing Of the dial, even if the daily use of minor scratches encountered, drawing lines can also be a good cover out. The curved edge is more comfortable to wear, the same for the skinny wrist.

35057671613_01dabbe598_c.jpg


Mysterious midnight blue dial, very attractive, from the overall colour point of view compared to a version of YL (before YL there is a fake version - not fully working calendar). You can see that YL also upgraded the colour, not much difference compared to the Gen. The dial also has (Sunburst) radiation pattern effect, the overall simple and generous in general is very beautiful for any occasion.

35866897495_89f6c64cca_c.jpg

35027408664_9e78797b0b_c.jpg


Month, date and week can be used, the previous version only date is fully functional.

35826145346_9ba39bd035_c.jpg


Power Reserved from sub-dial with different tone effect, same as the Gen, excellent work, and not reflective.

35027385084_f3bec769ef_c.jpg


Willow-shaped needle and Arabic numerals are silver-plated, the edge of the Arabic numerals have a smooth chamfer, the font position and space accuracy is very good, did not find the problem of crooked or any misaligned.

Watch crystal is the same with the Gen sapphire glass which is slightly arched shape (referred to as the lid crystal) cost slightly more expensive than the 5001/5007 crystal, also coated with a light blue film.

The original movement for the IWC Cal.52850 automatic movement, equipped with double barrel, on full wind can supply 7 days power reserve, and YL for the new independent research and development of the true calendar movement, the Power reserve measured for 4 days, although there are differences in kinetic energy (depends on how you wear the watch), but this movement can be said to be a breakthrough in the rep world, of course, there is no way to make the appearance of the movement function same as the genuine Cal.52850, but the overall layout It seems that the rank/standard is still quite high (High-end REP), a simple understanding is that this movement is from the Portuguese 7 days (5001/5007) movement with additional month and week display, to achieve the same function and genuine.

The parts of the clasp are the areas where seem to have the least flaws, whether it is the details of the drawing, and the handling of the edges and corners, or the restoration of the whole structure is perfect.

NOTES : -
  • Power reserve indicator is working perfectly. By turn the crown (without un-screw) clockwise you will see the hands is moving from empty to full (7 marks). Please do not over winding. Stop after the indicator rreaches7 days mark. And wind it again after the indicator on red area.
  • Do not expect the power reserve will be 7 days. After my test, it is only 48 hours straight with no issue. The indicator is pointing to the right marker, so you will know when the power is empty. You won't be misled by the indicator.
  • Pull the crown to the first position to set the date and day. Turn clockwise to set the date and the month. The month will move after you reach date 31. So you can not set the month manually, you need to turn date by date until reaching the correct month. Turn the crown anti-clockwise to set the day.
  • As the video above, you can see that on the normal situation every day, the date will start moving when the hour hands @10 o'clock and will be perfectly aligned @12 o'clock. Do not be surprised if you didn't see the day moving because it will start moving @ 2 o'clock.


CONCLUSION
  • The more complicated the watch, the harder to be replicated. Sometimes you need to accept some flaws on replica especially on the complicated model. Remember the price will always tell something. Do not expect 100% exactly like genuine.
  • Overall, YL has made this model replicated nicely, especially with the working features of the day, date, and month, also power reserve.

Great review. Thank you! I really want this but the gears being wrong colored and the black gear it does have just floating attached to nothing is a little much. I wanted this so bad to be passable. From the front its great. Then it turn it over and not even close :(

Thanks again! Love breakdowns like this.

I honestly hope they could correct all the spelling errors on the movement and the get the right font for the date/day/month wheel. After clearing up these trivial errors they could start making the 5027

Really enjoyed reading this comprehensive review on a beautiful watch. Do you think YL will use this movement in an upgraded version to the 5007?

Another impressively detailed and excellent review, Thermal. Only thing keeping me from opening up my wallet for this watch is the spelling errors. I hope it's fixed soon.
