I am a hobby watch-repairer.

Currently on the bench is a Seiko 6119C. After following the standard cleaning and lubrication procedures, the watch was running with extreme deviation. I removed it from the balance cock and trued the hairspring, which vastly improved the watch's performance (+/-4s). The amplitude continued read low on the timegrapher (~180°), and I found the barrel housing was warped. I ordered a replacement mainspring barrel, however the amplitude did not improve. I need to dissasemble the barrel to clean and lubricate it.

I use this 3D printed set of mainspring winders.
