Ok, got this pocket watch not working. Made a balance staff and cleaned it up and works great. Problem I had is that some bat watchmaker out a blob of solder at the 1 o’clock position on the case, to hold in the leaver that needs to be in to set the watch. So, I got out my torch, remover the solder. Then I took a piece of mainspring, doubles in over (using heat) and formed it to slide into the gap between the movement and the case: to hold in the leaver. Much better fix and works great. The beat error is a little high but the Amplitude is around 230, with a swing way over 450 degrees. And it sets the time wonderfully. Sent from my iPhone using Tapatalk Pro

Swap the circuit if you can first, because the height of the hour wheel / canon pinion / CS pinion vary between models. Certainly the one fitted to the Seiko Gen 2 Military chronograph differs to the newest movement available. Can measure the current draw later to see if it’s running well enough to give a thumbs-up.

a good cleaner is alcohol! find it at rhe chemists shop. vin

It's generally frowned upon to oil the pallet fork pivots. If you put the watch on a timing machine before and after you will usually see a small decrease in amplitude. If with time the lubrication gets more sticky that decrease of amplitude will be more dramatic. Seiko as mentioned above does recommend oiling the pivots sort of? If you go through their tech sheets sometimes they do sometimes they don't. The other strange thing for Seiko is if you have multiple generations of service sheets even for a particular caliber sometimes they do sometimes they don't and unfortunately they do not explain why.

Hi, My brother had a Rolex Oysterdate movement 3135 that did the same thing. It would sometimes change, other times it would not. Mechanism is probably the same. A gear broke several teeth. See attached pictures. ***16.jpg was a Rodico picking up some of the fractured pieces Hope this helps.

Try removing the seconds pointer and placing a ‘thread’ of rodico onto the shaft where the seconds pointer would usually be seated. Using your eye loupe you will see if the shaft is turning as it should and not intermittently. My guess is that the pipe which forms the interference fit needs very slightly adjusting to restore the interference. Sent from my iPhone using Tapatalk

Thats what I’m thinking... the teeth broke off. Can be many different things including the setting mechanism like the yoke or other elements may have become uncoupled. But the fact that the date doesn’t change either by quickest nor by advancing the time tells me it’s something at the calendar side. Makes sense? Hopefully it’s something that can be adjusted though!

I would say no. Dipping the movement complete is a bad idea. Quartz watches have many plastic parts in them that may react badly to lighter fluid, also it will not clean the pivots correctly. I personally think that pretty much everthying above is bad advise. Quartz watches still need to be dismantled to clean and oil correctly. Maybe if its a $2 watch and its not worth the time to service it correctly and you just hope to get a few more months out of it the above might be worth trying, but other than that I advise against using teh above cleaning instructions.

There’s a significant chance that the wheel that flips the date broke off. This requires a trip to your watchmaker for sure. Good luck. Sent from my iPhone using Tapatalk

Squeezing it with a pin vice worked. Thank you.

there is a fair bit on content in George Daniels book on making jewels, everything is done with diamond. good on you for solving the problem

good question, even when they are " rattleing" the watch is working. oil or thicker oil on the ball bearing might quiet them down. if you can't get a new one, try oil. good luck, vin

How did you know the bearing need be replaced. Simple clean and oiling may be all you need.

And, fleabay US has several listings for 7750 parts including an oscillating weight, complete with bearing. https://www.ebay.com/itm/Tissot-Rotor-Oscillating-Weight-for-ETA-7750-Swiss-Made/202598217838?hash=item2f2bcb786e:g:YsEAAOSwQFhbY1IL:rk:1:pf:1&frcectupt=true There are also 2 complete movements for sale in case you're interested in having a spare movement for your watch. Cheers, TD

Hi Dave; It's a bit hard to see which exact model you have and where you are located; but a quick search on eBay a seller in Canada has a 2nd hand for a 7750 ....... ? Perhaps a possibility ? https://www.ebay.co.uk/itm/Tissot-Rotor-Oscillating-Weight-for-ETA-7750-Swiss-Made/202598217838?hash=item2f2bcb786e:g:YsEAAOSwQFhbY1IL:rk:1:pf:0

Mark did a video about building own watch. Sort of inspired me to build up a custom watch. The dial and hands are custom handmade from raw material. The movement is automatic TY2706. The case 316 stainless modified a bit. Worn everyday and a great timekeeper

I will try it and once I get it fairly reproducible i'll document it. I will take a series of photo's and break it down in steps. I have used water slides before, I was just unsure of the thickness of the overall stack. I will give it a shot.
