I'm currently building a custom watch with an ETA 2892-2 movement. The movement is from an old Brietling. I managed to fix it and was working perfectly. I was in the process of putting it all together, was attaching the second hand and it suddenly stopped. I believe I may have used too much force. However, I have taken the watch apart again (about the 12th time!). I notice that when I move the hacking spring it stops as it should, but when I return it to the position that would usually allow the movement to move again it doesn't. I assumed I'd knocked something out of alignment, but to add to the confusion if I give the escape wheel the slightest nudge it continues ticking. It's baffling me.
Anyone have any ideas?
I have been asked by my stepfather to service his Sanford Bros HF 36000 automatic watch bought new in 1977. On starting work, I noticed its an ETA 2832 but on looking for the technical sheet, I can't find one anywhere. Perhaps it is a rare movement but maybe there's an equivalent document I can use. My first main concern after removing the rotor is how to remove the auto-wind assembly - looks quite complicated and this is only my second attempt at an automatic movement. I've added a few photos for reference. Of interest, Sanford Bros was a small watchmaking company in the '70s based at 321/323 Oxford Street, London W1. He still has the original sales invoice!
Would anybody be able to point me in the right direction please?
Join me as I strip down, service and review this Chinese ETA 2892-A2 clone. Seagull ST1812 watch movement. There was a couple of issues to deal with but altogether a fairly impressive movement for the price.
Im working on an ETA 2783, and suspect that the canon pinion is to tight against the lower wheel.
So I have to make it a little bit more loose...
Has anybody done this befor?
And how it the best way to do this?
ETA type of Center Wheel/Cannon Pinion
Working on a Tudor Oyster Prince with ref no: 2081/4 with a ETA 2784 movment.
Cleaned and inspected, all looks good, no sign of wear and tear on the main spring, no sharps bend, looks overall good. Noticed that there where some marks on the barrel wall. But that I have seen before witout any drama....
Oiled it , put togeher , goes like a dream..... but the the spring does not stick, it snaps over after 6,5 turns by crown.
So the question is:
Can I just replace the main spring?
Can I just replace the main spring and do something with the barrel walls ?
Buy a new barrel with spring? Is it to be sourced?
Ref 9081/4 is the ETA 2784

Dont know the longevity of watch straps as I have many watches and wear them at infrequent intervals but I can tell you about leather as I'm into leather as well as watches and I've made belts, wallets, bags, watch straps, purses etc. There are many different kinds of leather with the most durable and hardest to cut being stingray which also is the most expensive. I dulled a blade cutting 1 watch strap then there is alligator, croco, caiman, buffalo, cow, pig etc. and there are many different ways of tanning the leather. Tanneries can tan the same leather and produce soft or hard leather, leather with a grain etc. Full grain leather is the whole thickness of the leather and is the best. Top grain is the top layer of the leather after it has been split to make it thinner and produces the top grain and suede then there are the various fakes starting with PU leather which utilizes the suede left over from making top grain leather. They basically coat the suede with polyurethane to make it look like leather. If you ever bought a cheap belt and after a month it cracked on the top layer this is what you have. The suede part will hold up but the PU part cracked. then there is leatherette and another form of leather where they take the scraps, grind them up and combine with a glue and I think they call this genuine leather. A leather watch strap that is sewn together would be made from top grain leather on top or alligator or whatever and on the bottom a softer, more comfortable leather such as pigskin. Pigskin can last many years, I have a shoe lined with pigskin that I have for about 20 yrs. I put 5-7km on it daily and its lasted.
Hello everyone, I have a quick question on the video i referenced above. At the end Mark discussion about dynamic poising. He shows seven different positions results but at the end he just has three which is dial up, Pendant Down and Pendant forward(which im assuming is pendant up). My question is are you only supposed to adjust the watch in other positions to ultimately have these three positions the only ones that matter? Other question is what are the most important positions you should adjust for when it comes to wrist watches and pocket watches? I think I might be spending way to much time worrying about adjusting other positions on watch when i really dont have to be. I also know it all depends on the type of watch but if someone could give me like their general rules when it comes to this that would be great. Thanks
I have this Hamilton 974 pocket watch. It is running strong however the minute hand move stops at 12:05 everytime it is set at 12 o'clock (the watch keeps running after the hand stops). I've replaced the cannon pinion, and the center wheel (center wheel was a tiny bit bent which I thought was the problem). I've watched it running and all of the train wheels are moving but the hands are still stopped. Any ideas?
I don't have the tool with me unfortunately but I think all that was there is pictured. I think it is just whatever cutting tool that is described in the images that is missing. The top part of the Mimo tool is separate to the lower part which is labelled 1CR1, and the top part rotates freely on the base. The red balance wheel holders are then placed on the top of the tool. The first image in the patent is a vertical cross section through the two parts of tool, illustrating the bearing surfaces.
Interesting tool. Are there any other parts in the box? Are any hidden under the one marked "Mimo"? It just seems that something, or things, are missing, relative to the patent. I'd be interested to see the side view, and perhaps the other side of the "Mimo" part. Good job on tracking down some info on it. It looks like it might do well, providing it is complete. Cheers.
