Hey all,

So I'm not going to act like I'm an expert but I was speaking with occb2 and ado213 with regards to essential part upgrades for a SH3135 without crossing that threshold where you might as well as go gen 3135 calibre. Of course, gen parts will always be better but for those are stuck with one or want to use one, hopefully this will serve as a good reference/framework to help decide and also as the threads I searched for across here, RWG etc. were mostly inclined towards the older Yuki's. I've read a good service is the base minimum needed but to try and improve the % of reliability, even if only for a few years at most, is better than it crapping out. Of course, there's no guarantee, but hey ho, better to try and give it some TLC now rather than rely on medipak's later.

The below is what I have ordered thus far - mostly new in blister and rest either NOS or used/new. This listy below is based on my specific questions to occb and ado.

* 540 Reversing Wheels x2
* 625 Date Wheel
* 600 Date Indicator Seating w/ screws
* 614 Date Jumper
* 623 Date Finger
* 421 Pallet Fork

To give some ideas on the above list, below are extracts from conversations with Rob who thankfully gave me some of his free time to help me (hope you don't mind me posting):

If your alignment on the date is off then it’s the date finger spring and date correcting wheel which I change in every sh3135 as I also change the date plate itself part number 3135-600.

There really is no need to change the whole auto winding bridge. Just the reversing wheels and maybe pinion if it is bad.

Now Yuki had issues with the same things the SH3135 did with the intermediate date wheel stripping and also the date correcting wheel. So between 10PM and 2 AM it would put a lot of pressure on the intermediate date wheel and would strip it. Now the SH3135 is the same main plate as a Yuki so it suffers the same issues. Now JF had a different date wheel and I think that is why the main date plate 3135-600 is smaller. While their date wheel fits, a real one will jam. Easy fix is to either trim the date wheel, which I would never do. File the SH plate and remove the jewel that is there to hold the date wheel in place, which also works. Or buy a real Rolex 3135-600 part. That is what I do. Makes life so much easier and they can be had for under 200 bucks.

Good thing is the SH3135 did a lot of improvements on the reversing wheels. While they are still not Rolex quality they are better than the worn ones that came with the Yuki. Also Yuki almost always came with bent hand pinions. Sh3135 seem too be ok. Also Yuki use to sometimes jump 2 days when the date would flip. That has been corrected with the SH3135.

They are still dirty and dry as hell when we get them from china and need a good cleaning and oiling. They do use sub-par metals than Rolex but a nice serviced Yuki or Sh3135 can run you 5 years. Heck I have one in a watch I made that is running now on 3 years and still keeps perfect time. Yes it has about $900 in Rolex parts but the main plate and balance and train wheels and pallet and pretty much what is the heart of the watch are all still china.



Adrian suggested I may need a Pallet Fork (421) as "SH/Yuki 3135 pallet jewels are not usually set correctly in the pallet forks" but can't say until he see's seen my movement. I purchased it anyway el oh el wallet.


If anyone else wants to chip in feel free on essentials. I've read on older yuki's things like Mechanism Cover, H/M/S Wheels, Yoke Srping etc. are essentials, would these still be relevant for today's SH3135s? This is not intended to be who is right but more as a knowledgebase and worst case scenario, it only benefits me :)

Interesting read. From talking to different people, I have gathered the following list of parts:

To address Date Issue:
3135-614 Date Jumper
3135-645 Date Corrector
3135-204 Winding Pinon
3135-625 Date Wheel Mounted
3135-623 Finger for Date

To make it more "reliable":
3135-540 (x2) Reversing Wheels
3135-600 Date Indicator Seating
3135-670 Intermediate Date Wheel
3135-205 Sliding Pinion Wheel / Clutch Wheel
3135-280 Hour Wheel

Hope this helps. Maybe someone can chime in with the importance and level of reliability improvement with each part.

Don't you need the gen escape wheel for the gen pallet to work?

Oh really? Damn if so, will order that too! Think I've calculated total cost of all parts ordered the few extra ones the above poster mentioned to be roughly £700 but this includes shipping from USA, Italy and Germany. So let's just say £600ish.

Gen reverse wheel is highly recommended. One of my stock Yuki reverse wheel disintegrated (after a few months) and part of it got dislodged inside the trainwheel bridge. The movement was serviced before this happened.

I also recommend gen 3135-623 part because the one on the Yuki / SH 3135 is very delicate with just a jewel stuck onto it. Theoretically, changing out this part to gen would allow you to flip dates during the forbidden hours as well

Thank you :) I have both of those parts with me thankfully, sorry to hear what happened to you though!

How much is it?

This is what I have paid bearing in mind I've paid a premium to get them new in blister/NOS/repackaged NOS from USA to UK - total is: £609.88 for the part list lpl quoted - with the Pallet Fork 421 not on his list costing £68.99 new in blister so my earlier rough estimate of about £700 is on point when you take deliveries etc.

To address Date Issue:
3135-614 Date Jumper --> £0.00 (chucked this in for free, was NOS)
3135-645 Date Corrector --> £46.94
3135-204 Winding Pinon --> £39.72
3135-625 Date Wheel Mounted --> £65.00
3135-623 Finger for Date --> £34.67

To make it more "reliable":
3135-540 (x2) Reversing Wheels --> £101.44 (£50.77 each)
3135-600 Date Indicator Seating --> £176.95
3135-670 Intermediate Date Wheel --> £56.33
3135-205 Sliding Pinion Wheel / Clutch Wheel --> £49.11
3135-280 Hour Wheel --> £39.72

What if you had say the JF explorer 214270 without a date function? How would that change things and would it bring costs down significantly?

I'm not entirely sure with regards perhaps an expert can chip in but I'm going to assume perhaps the list of making it 'reliable' minur the date indicator seating.

With that said, for the price of that list, I'd rather just stick an ETA in if there's no date requirement etc. I used to own an OP 114300 and rather than get the SH3132 serviced etc, I just got ado to stick an ETA in from a Tissot and only cost me £190.

What eta hands did you use?

I have the Explorer with Sh3132 and I think the we just need a good service, Gen reversing wheel and stop. I swapped the reversing wheels on mine and is working good, more power reserve when used on wrist.

androme are you sure that for the wrong DW positioning on the SH we need to change the date finger spring and date correcting wheel? Because they simply manage the date change but the problem is the positioning.
