Hi jdm, thank you for your interest. I have worn this wonderful watch every day for nearly twenty years and there is a fair amount of play in the bearing, not rubbing against workings or caseback yet, but noisier than it used to be.

What's wrong with that one? Some play / noise is normal.

Thats incredibly bad news. I was sure that this would not happen with the genuine article. I didn't order from Cousins and it will probably be a hassle for me to complain.

And the official answer from Bergeon is the worst. When you are a customer who has paid good money for a product that is defective, you do not want to hear "Well, we acknowledge that there is an issue with your product that renders your purchase useless, but other people have not complained, so you should be fine"

Please advise where I might purchase an oscillating weight including bearing for a Seiko 7S26A, I live in the Eastern Cape, South Africa. Thank you.

Hey guys! Great information here. Teaching myself some basic watch maintenance. Really just starting out. Bought this with a view to "learn by doing". It wasn't winding when I started. Had an amazing time taking it apart and examining the parts. The hairspring seemed bent so I had a go at shaping it and damaged it even worse. The study came off and was lost, then part of the spring knotted ... Argh. I'm murdering this watch I know! I'm having a really tough time finding a compatible replacement. The parts chart says that the balance is "different from basic calibre 100" and to "refer to catalogue GF 239". I can't find any document by that name. If I could get some help it would be appreciated!
