I mountainbike with all my watches. You are however increasing the risc of damaging gears or the balance staff when doing rough stuff. But I'm aware of that.

-edit-

Nuchtere Hollander You'll never get this off the ground. No way. Never. Sorry.

Probably a defective reversing wheel. The main spring doesn't store/ holds enough energy.

Could be there are some small variations or alterations? My swaps were in early 09. With your info in mind i's wise to first ask about the hight of the canon pinion. Maybe there pinions are interchangeable? Are the members that know?

Never had any problems, noob and SSD.

Yup, the Asian is superior in regard to quick date set. Go firgure ....

Great job filming it. Nice and sharp film. What camera did you use? PS: Don't forget to oil and grease the different parts as the keyless works is under a lot of stress. Otherwise wear and tear will set in pretty fast as all the metal grinds against eachother. It's easy if you have some different oilers, the right oil and grease (D5 and PML) and follow the SwissL@b instructions.

Ah ok. A worthy contribution Red

Nice pics but there was no reason to disassemble the keyless works other than a educational purpose for this forum. All components were positioned just fine.

Keyless works looks fine by the way Nice tut.

that's the sound European chickens make Make it easy on yourself and use 'Paint'. If you want some help let me know! Cluck Cluck over and out

"Buck" "buck"... chicken?

For the money it's a good looking watch with a very reliable movement. Probably even more reliable than the gen

Beat error varries regarding to the position of the movement. 0.5 dial up can lead to 0.1 crown down (which is the position the movement is in most when wearing). Don't worry about it too much

That's a 1-on-1 swap.

I'm following this thread. If all turns out okay I might order one too.

Because they slip! Lately I'm getting more and more 7750s on the bench with slipping second hands. Or ones that slip when I reinstall them after service. Or sometimes I completely tear the hand apart from the tube when removing it and end up finiking 30 minutes to get it back in . Overal the most chrono second hands of our 7750 watches are poorly finished and mostly only suitable for one-time instalment only. After that the tube most likely has too much sl*ack after reinstalling which causes the hand to slip. And then there's the problem to make the chrono second hand in place. Due to the large force it's under from the hammer it needs proper friction to stay in place. Crimping the hand is almost impossible as when you squeeze one side of the tube the other side will get larger (still too much sl*ck). Glue is even more difficult to use in securing the hand as the pivot is very hard to reach. Therefore my hypotheses is: Installing the chrono second hand on a 7750 watch is hardest part of an entire service Just wanted to vent

No problem Mike. I made the post and I replaced the PF like 10 minutes after that I just did not want to tinker with it any longer. So I too forgot about this post, otherwise I would have PMed ya Thanks for your elaborate answer though!

+2 imo best option is Asian version and have it serviced.

And it has the clean bezel so maybe they will make the other models with that same smooth bezel ??

Buy a scratch pen and brush in 1 direction. Search for scratch pen on ebay and you'll find what I mean (sort of glass fiber tip pen) also available in a many car part stores for brushing away rust.

I think you guys are right on the money! Too bad . That's what you get if you replicate from pics and not disect the real deal
