Yes.

No. One dip is perfect. It evaporates. Water could stay in cracks and cause rust so never wash. I prefer a tiny amount of D5 on 2~3 ball bearing. A slightly higher viscosity makes it even more smooth than 9010.

Don't expect miracles from one dip. It is just a fast drying cleaner. All other naphtha based fluids would also do just fine IMO.

Be careful not to dislocate or loose the balance hack when you remove the auto wind module. Make sure you have proper screw drivers for the rotor screws as they are tiiiiiiiiny!

@ Rolexman,   This review was a pleasure to read. This community is great, thanks in part to the wonderful efforts of members like you sir. I truly enjoyed this, as I gather every other reader has. Blessings   D

How do you even access the mainspring in the barrel?

Thanks rolexman but I don't feel like I've learnt if I do that. I rather spend £50 and find out I can't fix it and have learnt something than just hand it over and be none the wiser. If I can't repair it then ill probably not both doing anything more.

The mainspring is £12 in the UK but I assume that's not the full barrel assembly.

1. Check the end shake (ok?)

2. Check if the hair spring touch-and-releases the rate regulating stud (ok?)

3. Check if balance staff pivots are (ok?)

4. Turn balance and determine if all coils are spaced equally (ok?)

5. Check the jewels of the gear train for cracks (ok?)

6. Diassamble the barrel and look at the barrel wall and clean oil main spring.

This last step can even be dangerous if you never done this before as the main spring is packed in the barrel with a lot of force.....

Edit:

In between step 2 and 3 I would recheck the pallet fork if it moves freely. Wind the watch and gently tap the fork. It should move on it's own 1 teeth of the escape wheel and than lock.

Good luck!

What causes low amplitude? The mainspring? Worn out/damaged?

That's why I serviced it. It's an old watch (my first ever rep) and I wasn't too worried about the outcome.

Should I buy a new mainspring?

Regulator studs touching the hair spring, coils out of sinc, broken balance staff, broken jewels, damaged barrel wall etc etc. Unfortunately....

Just bring it to a local repair guy. Otherwise you will spend all your money on parts you may even not need.

Well you now know the right settings... It's time for me to tell you to throw that winder out the window

No seriously. Having a watch on a winder gives you the pleasure of an always running watch for you to put on whenever you like. But it also means it is under constant strain and wear and tear will increase. It is like having your car running on a Dyno roller 24/7 at 100 mph. If your engine is a piece of sh!t it won't take long for it to break down. If your engine is in top notch condition however it will not matter as long as you give it it's maintenance on time. Where a normal movement needs to be cleaned and oiled every +- 5 years, even if you don't use the movement as oils will dry. A constantly performing movement will need service faster as oils will gumm up.

So if you have stock non-serviced A7750s I personally would not recommend a winder.

Yup... amp way too low. This won't keep accurate time on the wrist.

Check the end shake of the balance. That is the vertical play between the balance jewels. You can only do it if the balance is at rest. If there is too little end shake it causes too much friction. Ergo slow en short balance swings. IMO this topic should be over at 'movement Q&A'...

Great monologue.... Glad to see you figured it out

The jewel probably came out because you mounted the pallet fork bridge the wrong way like wOlf indicated. This caused the pallet fork pinion to push out the jewel. Be sure to get it on the right way next time by looking at the screw head slots (was also mentioned by wOlf)

Have you replaced the crystal with a genuine crystal? The way a bezel fits on a Rolex has to do with the crystal. After market crystals tend to be slightly thinner/smaller, which allows for more play in the bezel's fit on the case.

Could you elaborate on that? I thought the retaining ring combined with the washer and click provide the tension to the bezel?

Not on a plexi crystal; that's a 1675.   Polish the scratch out of the crystal   Buy a clark's crystal  and replace it (~$25)   Buy a gen crystal and replace it

Cool project you have going on.... Can't wait for the update. Some real craftsmanship!

Something is wrong with either your gear train or pallet fork / balance. Check by removing the balance and pallet fork. If your escape wheel won't turn if you wind, you know it's the gear train. If it does the problem lies with your pallet fork or balance wheel.

Let us know.

The cyclops is a loose part glued to he crystal (GS hypo). You can replace it with a new one if you know your way around watches. Otherwise you are better off sending it to a watch maker. I separated some with a small chisel or even with a hot stove. In the last case one needs to remove the crystal off course and it was not a plexi But you really need to know what you are doing otherwise you will ruin the watch.

Here's a comparison of the gen clasp cornet and the 'cartel' version.

Thanks for the feedback. Very kind of you. Glad I could be of service!

This should be titled how to get 2-5 teeth knocked out (depends how strong I'm feeling).

I've never seen a 19mm folded-link Rolex rep bracelet, unfortunately. wiesn089 compared solid rep bracelets a while back, and the Yuki 78350 looked good for the price.

Thanks!!!

Preferably folded links and clip on end links.....

Does need the proper markings off course.

Thanks for the tips

Cheap DG2813 21j. Worth about $11.00

If they run ok they probably run ok for a long time....

Performance picture after break in of the movement added to my first post!

The watch and movement is now for sale: http://www.rwgforum.net/topic/155150-famous-rolex-yachtmaster-ultimate-a3135-from-the-review/?p=1192192

Amazing post. Thanks a lot for this. Does the Y3135 have a freesprung balance / real balance screws?

No on both accounts. The A3135 has microstella screws that are for show though.
