Actually I am more concerned about the value.....does it mean that those w/o the "superlative chrono official certified" are older versions?boobip said:Those with the chronometer certified means the movement have been sent to undergo official tests and certified to deviate within a stringent error margin of between -4 to +6 sec per day. This certification is valid for only the first 3 or 5 years (can't remember exactly).
My Dweller is a S series 1993 in very good condition. it's a Tritium dial with SEL bracelet, brand new bezel and full links. Importantly, the movement keeps time within +3 sec deviation per day. At SGD$4500, I think it's a wonderful deal for a watch that's 13 years old.
Btw the way I also think your SD is a good buy at $4.5K...somemore wif brand new bracelet and bezel....can know where you got it from?
