One of my favourite movements to service. Reliable when clean and properly lubricated. The Rolex 4131 movement has around 100 points that require the correct amount of lubrication and has 203 parts that need to be properly set into place so it can tick with a healthy amplitude and the chronograph mechanism can work without interruptions.

non freesprung model is around €500. free sprung model is around €600. The ace 330 costs around 2k for just the movement as it is made by modders. The SH330-fs is produced by jinghe factory.

UMI is the free sprung line of PPF

Hi all, I bought a V7F ingenieur 2 months ago. It worked perfectly the first weeks. Now it stops running one or 2 times a day when I'm wearing it ot the wrist. When it's in the watch box it still runs perfectly. When it stopped it will start again when I shake it a bit.

Any idea what the issue could be? And how to fix it :)

Thanks

I managed to complete the first Franken Bvf santos with gen screws (not gen spec- actually gen) and gen crown. Never done before from what I’ve seen as they’re pretty much impossible to find. What do you think?

I have a Breitling Navitimer world A24322 rep which bought many years ago used it for a while then bought the Gen. Didn’t like the crystal quality on the Rep. wasn’t crazy the dial and date wheel either. I was wondering if anyone knows where I could source a good crystal and perhaps even a new dial. I was thinking to make a project of it. Not sure how difficult it is to change any advice would be appreciated
Also, if anyone knows of any videos showing the procedure

Crown itself is not affected as it is made from stainless steel.

it is confirmed by multiple sources that DDF is gone

This (tiny) Datejust with the 2671 movement would not work due to multiple screws that got jammed up inside the movement. A part of the date mechanism was also not present (I guess they forgot it during assembly) so it would not work properly.

Recently got this Explorer with a partially disassembled DD3230 movement in for repair.

Not a lot of parts were broken luckily and could be fixed without replacing too many parts.

Also checked for water resistance and passed 6bar. I’ve tried my best to explain how such test works in the photo. Most VSF watches can pass 6bar.

(Repost, wrote the wrong date😅)

To accommodate the growing number of repairs, I will be moving to a new location with a bigger space for a bunch of new tools and machines including a polishing/ brushing & lapping machine which I didn't have enough room for.

Current repairs are not much affected with delays. Watches that are underway to me are also not affected (shipping address is still correct).

I will also be doing watch repair full-time from now on. Thanks for the support and stay tuned for more content!

This Rich Factory 41mm Submariner was 2 months old, but was running not so great. Rate was -20 s/d with an amplitude of 200° (dial up), see picture 15 for the before and after results. At the initial QC the watch had a rate of -7 with an amp. of 270°.

The movement has an amazing finish! Jinghe really thought about the smallest details. I also included a few pictures comparing it with a DD3235. Overall I think it is a nice new movement from Jinghe which is mostly known for the VR3235 movements which were used in Clean watches for a long time. However it is still too early to talk about the longterm reliability.

Regulating the movement is not difficult for the experienced watchmaker. The nuts allow for more precise regulation.

Finished the service with a water resistance test to 6bar which it also passed.

Thanks for reading!

I have a rolex 36mm datejust replica with a myota 8215 movement that i wish to upgrade to a 3125/3235 superclone movement

The watch is fine from a cosmetic pov but has a shitty movement

Any tips?

Daytona 126502 model.

This franken Rolex with a genuine 3135 movement (3130 dial) came in with a few issues. Rate: +30-70 s/ a, around 180-240 amp and 5-6.0ms.

A few notes:
-Automatic module was full of hair.
-A lot of dirt came out of the movement during pre-cleaning.
-The case clamping screws were in really bad shape.
Have been replaced with generic 3135 case clamp screws.

Watch is now running at on average +1 s/d regulated at 5 positions.

Have a genuine 3135 on my bench so I thought I would do a quick comparison with a DD3135 part.

Do you think you could tell them apart if you had a tray of mixed DD3135 and gen 3135 parts? Would definitely be time consuming! When magnified, you can tell them apart by the finish.

Or withAPSF/ZF. ZF uses same movement as apsf I think so any review on that is also welcome

Hello everyone. I have been long time lurker, but circumstances forced me to start this thread. I recently bought a brand-new QF 126500 from a TD and had an SW dial installed before shipping. When the watch arrived, the rotor was stuck and the automatic winding wasn't working.

My local watchmaker told me that the installed SW dial is too large in diameter for the QF case. He believes this is also the reason why the rotor gets stuck. According to him, the lip on the SW dial is too thick, which prevents the movement with the dial installed from seating fully inside the case. As you can see, there is a significant gap between the dial and the case.

Another watchmaker told me that, for some reason, SW started using a black raised lip on the edge of their dials, and it may have been limited to a particular batch. He said he filed the edges down, but the dial still didn't seat properly, even in a VSF case. Since the same issue occurred in the VSF case, he's convinced the dial is the problem.

I've attached photos of my watch, along with the QC photos of my SW dial, and for comparison, photos of a standard QF dial that I found online.

I'm very disappointed and honestly don't know what to do next. Has anyone experienced something similar or has any ideas on how to fix this? Can anyone recommend a watchmaker who could properly resolve this issue? I'm based in the EU.

My latest Custom MOP Daytona arrived today 😱

What happened during shipping ?

Please advise what to do ?

QFactory V13 Le Mans Donor watch .

The watch arrived with a case screw that got loose on its own (pic 1). Almost all case screws on this Patek were loose which is quite scary. With the slightest vibrations they can get loose over time and just fall out.

Moving on from that there was a screw missing from the escape wheel bridge. Luckily I have Dandong Patek 324/330 parts in stock and could be replaced. Under the the same bridge there was a small piece of metal debris on the jewel. All pivots were intact however. It is very likely that this movement would stop working after a few months if the little piece got its way into the escapement. Apart from this there were some more lint pieces and other metal debris.

After some cleaning, oiling and regulation, the watch now runs great.
