They're cool watches! I fixed up a pair of light colored dial ones about a year ago (now passed onto others!). Its a pretty neat movement, and I found that the alarm complication is really fun/useful, if not particularly accurate.
Yes I would not use it to wake me up for work
Nice 4005! Great everyday watches with a very useful complication ⏰ Your timegrapher trace isn't too bad as the stated lift angle on these is a massive 58.4! (Probably incorrect) But these can happily bump along at quite a low amplitude but as ever a service wouldn't go amiss.
Unfortunately yours isn't on its original bracelet these are the 3 they came on:Check out this thread if you want more info on Bell-Matics: https://omegaforums.net/threads/calling-all-bell-matic-fanatics.159973/post-2184566
