found this one on the Bay, anyone know if this one is legit, looks a beaut. Only one photo which does make me suspicious.
Looks just fine.. it’s not a watch that someone’s gonna want to fake, since it’s an unknown brand. And from what I can see, the dial looks untouched.
maybe ask to see the case back, and that all functions are operating well, then…
Nab it!
Cheers mate that's what I thought just thought I might get confirmation from the esteemed members of OF. What do you reckon is a reasonable price range for one of these? I thought maybe 800-1200.
Congrats, I always wondered where all these NOS Trematic/Keystone comes from.
I have a grande total of two, now 😝
I've found very little information on the brand, as has many before me, but Mikrolisk states that the company was formed by E. Petremand in Colgny (part of Geneva), Switzerland on April 12, 1952. All of the examples I've seen have the noteworthy Felsa Bidynator (very first bi-directional auto) movement inside.
Here's my tiny collection 😀, a ref. 602 (Moonphase) and a ref. 502:
... interestingly, here's an auction from a few years ago that was selling a Trematic TDMP (ref.602) like mine, but it had the 'Tiffany & Co.' name on the dial:
I know there's a small number of Trematics among our members, so please do share yours, and any information you may have on this seemingly 'phantom' Swiss brand!
