I have replaced the capacitor in this JDM Seiko AGS Spirit Titanium (5M22 movement). This is a one piece case, so the bezel has to come off to get to the movement. The bezel gasket was a bit hard to get back in (ordered two new ones and ruined one), but it all went in on the second attempt (using a drill press. Yes, I am a newb and do not own a crystal press. But I have other tools and am resourceful). Here it is. I really like this watch. It's very well made, the titanium case and band make super-light and very comfortable watch. The crystal is most likely sapphire, though it does not say so on the back. I did look up the Seiko catalog and it calls for sapphire replacement part. Also, for a watch this old (from the early-mid 90's) the crystal is literally pristine. No scuffs or scratches. Very high quality piece that I am really enjoying right now. The new style capacitors (LiOn batteries, really) allow about a 4 month reserve on these. I am very happy with the purchase and the "service" I gave it.
Watches of this vintage could be of either 2209 or 2409 variety. The 24 series is still being produced and new parts are still available from meranom in Russia. The 22 series is archaic .parts must be cannibalized from other movements. These can be purchased by the bushel online. CHEAP.
I am a newbie in watch repair. Recently bought a zim 2602 watch, it produces strange noise, and stops. The volume of the noise depends on the position of the watch, tends to stop rather in face up position. My guess was that the hairspring touches something, but I wasn't able to prove that visually. I attach a file about the sound it makes and a pictures. Thank you any help.
