danielv2000 Posted October 17, 2013 Report Share Posted October 17, 2013 i have a swiss 2836 where the watch functions perfectly when wound. However, it does not auto-wind and loses its charge after about 2 days. Is this an easy fix? Could something be lose in there? Thanks Link to comment Share on other sites More sharing options...
misiekped Posted October 18, 2013 Report Share Posted October 18, 2013 Lose the charge while you wearing? Link to comment Share on other sites More sharing options...
danielv2000 Posted October 18, 2013 Author Report Share Posted October 18, 2013 Lose the charge while you wearing? Yes. It's basically turned into a manual wind. Link to comment Share on other sites More sharing options...
freddy333 Posted October 18, 2013 Report Share Posted October 18, 2013 Could be a number of things, but the auto-wind module is likely either damaged or installed incorrectly (not meshing with winding wheels). Only option is to remove, disassemble, inspect, correct (the problem) & reinstall. 1 Link to comment Share on other sites More sharing options...
chris5264 Posted October 18, 2013 Report Share Posted October 18, 2013 I remember reading somewhere....that you should not hand wind automatics because the gears are so small...if someone cranks on them...its easy to break off the teeth and then you need to replace the whole auto winding system....but this sits under the rotor...I've replaced a few on the 2824,,,so I think its the same deal if you get a good replacement...but that usually means finding a 28** that has something else wrong with it,,but the auto winding is fine...but if you can get the back off....the autowinding system is held on by a few screws and should lift right off..

Only option is to remove, disassemble, inspect, correct (the problem) & reinstall. This happened to me recently and as freddy says above, the gears to the auto wind assembly are probably not sitting right, it was an easy fix for my watch, I removed the auto wind assembly and re seated it ensuring the cogs fitted together, when the rotor spins you should then see the gears turning.

freddy333 Posted October 18, 2013 Report Share Posted October 18, 2013 when the rotor spins you should then see the gears turning. More specifically, you need to see the 1st wheel (mainspring barrel) turning relative to motion from the rotor. There are usually 1 or 2 intermediate wheels between the auto-wind & barrel, which may themselves move but may not be transferring motion to the barrel.

danielv2000 Posted October 19, 2013 Author Report Share Posted October 19, 2013 So, i took a look under the hood. It looks like my rotor is just spinning freely. I turned it clockwise a few times and then it basically unspun itself. Link to comment Share on other sites More sharing options...
SSTEEL Posted October 19, 2013 Report Share Posted October 19, 2013 In that case the retainer/latch to hold the reserve is failing. Link to comment Share on other sites More sharing options...

shirotenshi Posted October 19, 2013 Report Share Posted October 19, 2013 In that case the retainer/latch to hold the reserve is failing. But I thought daniel actually manual winded it and it hold charge for 2 days? Link to comment Share on other sites More sharing options...
danielv2000 Posted October 19, 2013 Author Report Share Posted October 19, 2013 If I wind it, it holds for 2 days but it won't auto-wind. Link to comment Share on other sites More sharing options...
freddy333 Posted October 19, 2013 Report Share Posted October 19, 2013 Remove & reinstall the auto-wind module, gently making sure the module properly mates with the movement & is rotating the 1st wheel before tightening the screws. Link to comment Share on other sites More sharing options...

If I wind it, it holds for 2 days but it won't auto-wind. Good point that manually winding holds, and auto wind shoots back when you rotate the rotor. Remove & reinstall the auto-wind module, gently making sure the module properly mates with the movement & is rotating the 1st wheel before tightening the screws. Agree with Freddy ^^^ Something not right in the gear meshing somewhere there. Link to comment Share on other sites More sharing options...
Rolexman Posted October 20, 2013 Report Share Posted October 20, 2013 Nothing to do with gears meshing. Your have a faulty reversing wheel. Easy and cheap fix for someone that knows what he is doing. 1 Link to comment Share on other sites More sharing options...
automatico Posted October 20, 2013 Report Share Posted October 20, 2013 "Nothing to do with gears meshing. Your have a faulty reversing wheel. Easy and cheap fix for someone that knows what he is doing." Agree. The reversers are one of the parts that can cause trouble on Eta 28xx autos if you do not stay on top of them. Rotor bearings can also wear out along with the little wedge shaped post cast on the plate where the crown wheel turns, especially if you hand wind the watch a lot. When you hold an Eta 28xx watch flat (dial up or down) and wind it slowly by hand...if the rotor spins it may be a sign of reverser trouble (dirty/dry or worn out). A little bit of spin is usually Ok but a lot is not. If it still spins with the watch in a vertical position, there is trouble for sure. Link to comment Share on other sites More sharing options...
