Hi all, First of all I would like to say I am new to the forum. I have been working on watches for quite some time now but this one has me stumped (mostly because it's my newest, least touched watch!). A little bit of backstory. This watch is about 2 years old, I purchased it new (Seiko SARB033). It ran fantastically, i got it down to +2 seconds a day and it was a very consistent watch. About a month ago it started losing time. Badly, around 1-2 minutes a day. I initially thought the regulator might have slipped out of position so i adjusted it up. But it still ran poorly, gaining massive amounts and then losing massive amounts. So, I put it on the timegrapher i recently purchased and found this. Does not look good. Can't get amplitude above 180 and there is a strange drop off on the lower line that comes around regularly. I demagnetized the watch and the balance separately, but to no avail. Beat error was also horrible (around 2.5ms), but i've adjusted that down a bit just so it could be read easier. What do you think guys? Escapement fault? Gear train? Slipping mainspring?
