IWC 7 Days Portuguese 5001 & 5007 Review and Comparison

Recommended Posts

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).

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 
29093589503_d7f3633693_c.jpg


Sorry, this is YL V5!! (Not V4) - same as everyone, can't keep up with YL anymore.
29093592383_cca41a9192_c.jpg


GEN vs ZF V2 Comparison: -
ZF V2 has removed the centre movement (circled in RED) and improve the whole plate to mimic the Gen.
29427048180_7e86f0ceb6_c.jpg


In Red in what improvement in ZF V2.
29682899436_88f97097e7_c.jpg


This bit of plate is very close to GEN includes the marking.
29093582903_124ca23b1f_c.jpg

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

29607180822_ac9d44d812_c.jpg


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.

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.

subdials: rep is more reflective

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)

Hands colour check, you can see at the back of the hands is purple colour but after scratch off the hands inside is metal.

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.

29718208085_6c4550fac7_z.jpg


7. Date comparison - YL print bit rough, ZF and YL 3D Print “AUTOMATIC" and "SWISS MADE" is well made.

29093601823_b623b89335_z.jpg


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.

29637107451_30703e2ba7_z.jpg

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.

29093601783_3ffda696a7_z.jpg


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.

Portuguese 5001 / 5007 steps to silence noisy rotor (DIY)

1) Firstly open the case back with friction ball or base back opener
29607178962_d8cb26a0ee_z.jpg


2) you will see there is a tiny metal plate sticked to the middle of the rotor (Red Arrow)

29091756214_3012e1a6d8_z.jpg

3) Slowly removed it with needle / sharp edge screwdriver then unscrew the middle screw.

29093602323_47bdee0719_z.jpg

29682918986_c42d1f1b4e_z.jpg


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.

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

Just had a really good read of this thread, amazing detail, thanks!

 

It has really piqued my interest in this brand of watch (damn!).

 

Do any of you enlightened folks know if there is a reasonable (if any) rep of the IWC Portuguese Annual Calender out there anywhere?
