Mine
I own two G.O. watches, as Art knows (Senator Karree Manual Cal 22 and Senator Navigator Panorama Date Cal 100). Both watches run within a tolerance of + or minus 2 seconds per day. To be precise, both run fast by about 1-2 seconds per day. I understand that G.O. considers its tolerances to be better than those of COSC.
Caliber 39
Anyone know the normal rate for a GO with caliber 39? Mine is in a sport evolution and my rates were +3 seconds after 24 hours, +8 after 48hours and +13 after 72 hours. Is this normal for caliber 39? Tom
Glashütte Original movements aren't COSC certified . . .
. . . so the usual parameters associated with the COSC don't necessarily apply. I can tell you my experience with six different cal 39 equipped watches, three of which have been sent in for service or regulation: the spread between the most and least accu...

I haven't performed any timing tests on my cal 22 yet, but . . .
. . . the initial peremptory checks are within a few seconds per day, and the power reserve is 40.5 hours, exactly within the specified 40 hours +/- 5%. Btw, the cal 39 that was "essentially perfect" was my very first G O, a Karree chronograph w/o date: o...
. . . and a few comments regarding rate accuracy directly from G O . . .
. . . which performs tests to DIN standards rather than COSC. Glashütte Original manual- winding calibers 22, 42, 49, and most of the tourbillons are tested in five positions at three temperatures, and must be within a range of -4 seconds to +6 seconds pe...
Art, I don't mean to pepper you with questions but...
Did GO happen to mention *why* the automatic movements are tested at only one temperature rather than three like the manuals? And what those temperatures are? Just wondering. If you don't know the answer, don't make a special effort to find out but next t...
By the way, Art...
Wempe Jewelers (on 5th Ave. in NYC) is currently marketing, rather heavily, a gold tonneau-shaped watch as a chonometer...that is being sold under its own name ("Wempe"). The watch is advertised as meeting "...the standards of the German Institute for Sta...
Nomos or Wempe?
David, I think the watch you're referring to may actually be made by Wempe the watch manufacturer that operates out of the Glashütte Observatory. I believe the manufacturer Wempe is a different entity from the jeweler Wempe. I may be completely mistaken a...
No, I'm correct, Downing
Wempe the Jeweler (I work near it) and Nomos the Glashutte-based watch maker. It really is a "DIN vs COSC" thing, marketing-wise, as I said in my prior post.
