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 Standardization (DIN)...." The watch in question was built for Wempe by Nomos, which is another, smaller, Glashutte-based manufactory.

Post unification, the German Town of Glashutte is the home of those who have successfully re-established the historic German-Swiss rivalry...and is the home of German watch makers who have clearly eliminated the post WW II Swiss monopoly on high-end watchmaking The juxtapostion of DIN as an alternative credential to COSC is part of that. Frankly, it's both fun to watch and a win-win for all of us who love the craft of making high-end mechanical watches (it's like a replay of the old Celtics-Lakers rivalry from the 60s and 80s). A terrific national rivalry...brought about in part by the emergence of Glashutte Original and Lange as two top-tier world-class watch brands that now go toe-to-toe with any of the best the Swiss have to offer.

"COSC??? We don't need your steeenkeeeng 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

. . . 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 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 t...

. . . 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...

. . . 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...

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...

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

I stand corrected!
