thermalboyz 0 Posted April 16, 2016 (edited) History of the REP IWC Portuguese 7 Days 5001: In 2008 the REP Maker came out with the first generation of IWC Portuguese 7 Days (Ref: 5001). This version was not even close to the GEN 5001 as the Sub-dial spacing was too close, sunken date, the No: 4, Movements plate, prints, etc etc etc. After 7 years of waiting, in AUG 2015 ZF and YL join forces to research and developed a new movement which elevates the REP IWC 5001 to another level. They bought GEN and spent many months doing research to make the best IWC 5001 and finally they've succeeded. This blows a lot of people mind on how possible this 7 days movement can be replicated because this movement was built in-house by IWC and have taken watchmaker many years of research and study. Here you go, the year 2015 is the year of IWC and not only the 5001 but also other great IWC rep from ZF and YL. By having this movement repped, it opens up lots of opportunities on IWC model such as Annual Calendar (IW5035). RWI Dedicated 5001/5007 Portuguese 7 Days Discussion: (Lots of Information) [/url] Following are the first model from 2008: IWC 7 Days (5001) details specifications: - YL and ZF are making these, same movements. YL Released it first, ZF will take times to perfect it. ETA OCT 15 PR = 3 Days (Working PR Subdial) (72 hrs - been tested and confirmed by many owners) Price est: $350 Size : 42mm x 14mm Strap: 22/18mm Length: 135/55mm (deployant) Movement is collaboration of YL and ZF (Base on Asian 23J automatic movement) Spare Parts might not be available Low production capacity Model: White/Gold, Laureus, White/Blue, Black/Black, Ardoise, Panda. Comparison ZF and YL 5001 This info is gathered from Forums, users and personal findings online. I will update this table from time to time when new information available. Credit to all contributors. PM me if you have any info to add regarding this specific IWC 5001 Comparison (ZF and YL) ZF YL PRO Dial Colour – Yellowish (Same like GEN) Rotor – Better looking Case – Same dimension to Gen Printing – Wording on ZF looks close to Gen Hands – Better finish Case – Maybe on V3 unknown Subdial – more reflective Numerical Crook (misaligned) Fonts - IWC Schaffhausen (not same as 5001) but maybe same as 5007 Price – ZF more expensive Crown – Pushed in fully Subdial – less reflective Numerical Crook (misaligned) Fonts - IWC Schaffhausen (not same as 5001) but maybe same as 5007 Price – YL Cheaper Crown – Cannot pushed in fully CON Rotor movement noisy Hands – Not as good as YL Dial colour – too White Rotor – different than Gen Rotor movement noisy Crown – Cannot pushed in fully Printing – Not as good as ZF STRAPS DETAILS : - (Credit to GenTLe (RWG)) Many were asking if Curved End strap can be installed in 5001 like in 5007 model. Yes, they can but you will find a big gap when using curved end strap because 5007 have closer lug holes to the case than 5001. (comparison below, straight vs curved strap) You decide which one best suits you! ZF & YL NEW MOVEMENT DECORATION (27/11/15) Comparison of the new movement: - (ZF Estimate End of DEC out) YL already out - called V4. ZF new movement deco is closer to Gen. There are differences between the two new plate if you look closely. YL movement deco ZF movement deco YL movement deco Sorry, this is YL V5!! (Not V4) - same as everyone, can't keep up with YL anymore. GEN vs ZF V2 Comparison: - ZF V2 has removed the centre movement (circled in RED) and improve the whole plate to mimic the Gen. In Red in what improvement in ZF V2. This bit of plate is very close to GEN includes the marking. Top movement compare: - 1) Added IWC marking 2) Correct side with markings 3) Fixed escapement wheel beneath the longitudinal structure of the splint screw (still slightly different than Gen but lots of correction been made) 4) Copper plate fixing similar to Gen Bottom movement compare: - 1) 3 wheels alignment changed, closer to Gen. 2) Marking on the side similar to Gen. 3) Copper bit fixing plate location similar to Gen. Link = Dial Measurements from Master DOMI (credit to Sharrkey) Colour Difference: Rotor Difference: Fonts Details: There is two version of Gen 7 Days (5001 - Pre 2014 and 5007 - Post-2014) I won't get into the comparison between the two but what I want to point out was the Fonts of these two was different. Therefore I think ZF and YL are more on the 5001 dial/ fonts. (Credit to rhc22, sub007 and Ruski91) Black Dial Comparison: (Credit to diaby2afc) Gen dial - more glossy Rep dial - more matte subdials: rep is more reflective Laureus GEN vs ZF vs YL Note: Not all GEN are pointing at 12 O'clock direction so this is just a REF. Most complete comparison of Laureus, credit to 小陳玩复刻 Movement Details: ETA uses a type of ball bearing automatic disc on the gear structure, the gear structure is currently used by the vast majority of the watch, the durability of this structure is very positive, but not very on gear efficiency. Seiko Magic Lever is a hook jaw which cannot be compared. So - On Gen, more than 10 hours to be worn over to get to the full wind, and REP I guess it takes more than 20 hours of normal wear to fully wind. Power Reserve on REP is actual 72 hrs and Gen is 168 hrs. Movement type engraved on GEN is 51011，but on REP is 61016. Gen beat rate is 21600 and REP beat rate is 28800 (Better!!!). Movements research reference based on Panerai P.3000 case, by China made 23J with left sub-dial for Sec and Right for the PR (Power Reserve indicator), polished to the details to mimic 1:1 Gen. 5001 Movement from the front looks like 7750, back looks like ST25 (based on the big and small wheel). Looking at automatic mechanism plate, (similar to 2824) Movement Reliability: Case Comparison: Deployant/ Clasp: (Credit to vingsam) For Regulating : Use these two bits Crown Details: Gen have about 0.5mm Gap Blue hands investigation: Hands colour check, you can see at the back of the hands is purple colour but after scratch off the hands inside is metal. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 10/01/2016 - NEW Version Comparison (Gen vs ZF v2 vs YL v5) - Latest model comparison!!! Credit to 万嘉名品 Here is a TEARDOWN and movements details review from ROLEXMAN (RWG) and Chris3007 (RWI). Very informative and insight of movement reliability. >>> CLICK HERE 1, CLICK HERE 2 (Credit to ROLEXMAN and Chris3007) 1. LOGO Comparison - The fonts are doing well from the 3D printing. 3D printing font technique makes the print raised. GEN IWC used 3D printing technique. 2. Cannon Pinions 3. Hour Hand Comparison - Gen is flat, ZF little curved, YL lot curved 4. Minutes Hand compares - Gen Min slight curved. 5. PR subdial compare - all have a concentric circle, ZF PR hand slightly longer. 6. Sec Subdial comparison - Gen subdial and hands are even (In the middle), ZF hands slightly longer, YL at the outer ring. 7. Date comparison - YL print bit rough, ZF and YL 3D Print “AUTOMATIC" and "SWISS MADE" is well made. 8. Date Print Compare - ZF and YL do not have 3D Printed Date. 9. Index and Numerical - there is two Gen dial (One is a bit dirty), ZF and YL Edging is alright but different in colour, ZF bit darker, YL bit lighter. GEN bottom is white, ZF and YL bottom both blue. 10. Movements Comparison ROTOR 11. Movements comparison - Many people not keen on new movements and don't know about it. Today this movement has a name and called Dandong c.61016. because it was produced in Dandong. Movements LOGO, deco/plate and stamp of ZF and YL really good, Shock resistant part on ZF looks a bit different. Note the difference of the Barrel of ZF V2 and new YL V5, ZF did not cover Barrel with the plate but YL did. These are the changes YL did until the latest version they called Version 5 (V5). ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Update: 17 April 2016 ZF V3 and YL V6 (5007) model comparison New comparison and still not perfect yet on both factories. Following are the difference highlighted in "GREEN = better" and "RED = worse" compared to the Gen 5007. DIAL : - As a summary, ZF dial looks more on 5007 as fonts had changed however the YL still using the 5001 dial with larger fonts. ZF still crooked "1" and YL no crooked. MOVEMENTS : - Movements deco have room for improvements on both factories. In general, I think ZF has done it better than YL overall, however, lack of 3D effects on the movement deco and yellow colour plate at the corner of the movement (Gen is white). YL done a bit better on engraving the IWC stamp and wordings on the deco plate and also looks more 3D (Especially the 2 barrel wheels area) but the middle small wheel is not connecting the two barrel wheel. SUMMARY : - You make your own judgments on which one to purchase as I've pointed out the differences. Hope ZF and YL can refine the following that I've pointed out. ZF V3 backplate : (14/05/16) Update: 02/06/2016 Portuguese 5001 / 5007 steps to silence noisy rotor (DIY) 1) Firstly open the case back with friction ball or base back opener 2) you will see there is a tiny metal plate sticked to the middle of the rotor (Red Arrow) 3) Slowly removed it with needle / sharp edge screwdriver then unscrew the middle screw. 4) Take out the rotor, apply silicon (Waterproof oil) on the outer area than the inner area with moebius 8000 watch oil. Clean it properly ensure no excess and put back the rotor and case back. Edited January 18, 2018 by thermalboyz Share this post Link to post Share on other sites

Wriggles 12 Posted May 6, 2016 this movement have a name and called Dandong c.61016. because it was produced in Dandong. Great thread. Just been reading up on WUS about the F72 project watch, they appear to be using the same movement, they refer to it as the Liaoning Peacock SL6601 Considering Dandong is a city in Liaoning province it makes sense, just thought it might be worth mentioning Share this post Link to post Share on other sites
peteins 3 Posted May 14, 2016 Updated 14.05.16 Any other updates to the zf other than the now silver as a pose to gold small plates on the edge of the movement? Its difficult to see from pictures Share this post Link to post Share on other sites
tabuktime 54 Posted May 18, 2016 Just had a really good read of this thread, amazing detail, thanks! It has really piqued my interest in this brand of watch (damn!).
