I think the practical solution is a simple dehumidifier in a closed door room. That should be enough to allow the air to be dry and not have condensation when the owner wears the watch.

Movements should run without needing to be tapped, banged or hit about. Getting it to run by banging it around is either going to damage the delicate parts, or mask a problem that will only return... If your car doesn't start, hitting it with a 10 lb maule may work, but only for a while, the pivots on the balance staff are thinner than a strand of your hair, it takes very little to bend or break them.

It could be one of hundred's of reasons, without being able to examine it in detail and in person, there is nothing more than can be done. It's fully wound, there isn't much else you can do. If you had a local watchmaker it would be worth having it looked at.

I never claimed that they were the most intelligent or graceful animals in the Canadian forests. Similar to the British sheep, soon after they are born, sheep spend the rest of their lives trying to commit suicide...

Well done and well documented. Only until you have attempted a job like this and tried to photograph it along the way, can you appreciate how difficult it is to stop what your doing and get the camera out...

Wow, that is a bargain. Congrats.

It looks great, well done.

If it's removable you take it off, and hopefull can re-install it straight. If it's not removable it's virtually impossible to fix, you would have to do some micro painting/luming to fix the misalignment, which is very difficult...

The seconds hand size is actually 0.30mm, the 0.80mm measurement is that of the top of the cannon pin inner diameter where the minute hand sits on it. This should make it easier to find a hand, or at least one close that can be broached.

Great report, brings back memories and feelings of my last visit to Paris almost one year ago. Thanks for the details and great photo's, your making me lonely...

Welcome back Bill, nice to see you around.

Great comparison and write up, good photo's as well, well done. Thanks for posting this.

All the best...time for that new "C" class I think...

I noticed the same thing, must be on summer vacation or something...

Send it back to the person who did the repair...

It is one of the standard references for watchmakers. Mr Fried did many - if not all - of the line drawings in the book, extremely talented individual. Glad you like it, enjoy.

Me too, but it's just too expensive when all the time and parts are added up, adding another $80+ to a servicing is pushing the limits on a Asian 7750... Better to buy an ETA to replace the Asian one.

If you have stripped the gear in the first picture on the initial post, your out of luck, they are not available. The only option is to turn your auto into a handwind. Keeping it as is, will probably distrubute the metal filings throughout the movement and cause more damage. It is very difficult to diagnose a problem without seeing a watch in person. There should be a "click" sound heard as the rotor winds the watch, the part making the noise is ironically called the "click" and in the case of a 7750 it's actually a spring. So it may be normal, but the low PR isn't normal, could be one of many problems... PM is open, see my Sept/Oct booking post.

@ Nicewatches and Drulee PM's have been sent explaining why I had you blocked. Nothing personal, just something that made me uncomfortable and unsure, have a read of my message and I'll wait to hear from you. I never claimed to be perfect, it could be a simple misunderstanding based on what you had sent to me originally.

The only hands that won't fit are the subdial ones and the center chrono seconds ones. I modify all of them to work and fit on the ETA 7750, why not simply send me the hands, I'll modify them and test fit them in my shop, then send them back and you can install them...easy solution to your problem.

If any watch is of value (emotional or financial), it needs to be serviced regularly. I have a Doxa Sub 200T Graph in house now, very complex and rare movement that hasn't been serviced for a long long time...I'll post some pics. Basically the setting wheel wore down the mainplate pivot arbour so much the gear moves from side to side, this in turn caused intermittent hand setting and higher than normal crown friction when setting the time, which in turn finally broke a tooth off of the intermediate setting wheel...so as it stands now, the watch is DOA and no parts are available. I did manage a sort of repair to the worn out pivot, but it won't run with the missing tooth. The watch may never be able to be repaired, and these problems were completely avoidable, if only it had been taken care of and serviced regularly. Anyone who brags that they have (or know someone who owns) a watch that "...keeps perfect time, it's never been in the shop, in 25 years...blah blah...therefore servicing is a waste of time..." doesn't know what they are talking about and obviously doesn't care about their watch. Seiko's are great products, the quality of the movements is outstanding.

Yes, the land of the Beaver...our national symbol of pride...

My fall work schedule is FULL. Thank you.

I have some work travels coming up, as well as holidays. After today, I won't be around until the end of August. Email still works, but my PM will be turned off. I hope to have some new projects and information to share with my fellow RWG members when I return. Have a safe summer everyone.

Ohhhh, my....
