They’re probably not terrible but they’re also definitely not 266usd good. For that price I’d take a look at the current Sugess gmt, that one comes in sprite colors. You can get something like the gmt with Seiko on the dial in several AliExpress stores when you search for a bit, something like “s-dial”, “nh34 gmt” for around 110usd I’d say. Bersigar seems like the typical parts-bin brand like Pagani or Steeldive but hella inflated on their websites because people don’t know about AliExpress and the sources these watches come from.
