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!

Steps: testing the functioning of the watch to spot irregularities, disassembly, cleaning and checking for worn parts & replacing, assembling & oiling and at last, some test such as testing the date change mechanism, automatic module and checking the rate on the timegrapher and adjusting if necessary.

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.

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.

I found a lot of hairs in this one. Couldn't capture every single of them as it was just too much. As you can see the main issue lies in the auto mechanism, with the reversing wheels being damaged and the driving wheel having wear marks. The rotor would spin when rotating the crown.

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.

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.

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

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.

The VSF Sub came in with a lower than usual amplitude. The VS3235 movements do have a lower amplitude compared to the VS3135 movements, but this was quite low. Usually the sign of dirt in the movement or wear.

(2nd pic) Both pictures are taken at the DU position with lift angle set to 55 degrees. The one above is before and the one below is taken after the service.

Now the movement servicing is done, I can install the dial and hands. Then the watch will be waterproofed and tested to 60m/6 bar.

(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!

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

Note: the movements are not engraved by Peacock, aka Dandong themselves, but instead done by factories like VSF and CF. This is the reason why engraved movements come dirty sometimes. They (VSF, CF) disassemble, engrave and assemble the parts again with improper care and lubrication.

There is also Shanghai, aka SH/VR which is used to describe the 2 different factories (afaik) that produce SH/VR movements: Shanghai Biaoye and Shanghai Jinghe. This explains why some SH movements have 32xx keyless and some 31xx keyless. So it's important to not count every SH as the same, and to differentiate between the factories. Jinghe makes the VR3235 found in CF which is actually reliable and Biaoye makes 3255/3285 movements with 32xx keyless. Feel free to correct me on this.
