Hi, pls help me identify my vintage chronohraph 33.3 with blackandwhite dial. Why have the movement so low serial number? And i nowhere found the same reference number...? The second chrono is 2077 Thx Petr
Tissot used very similar movements which derived from the Lemania base caliber and they used such low movement numbers... Maybe this part has been taken from a Tissot movement for replacement of the damaged Omega part... just a possibility... Omega for sure did not use a 5 digit movement number on a cal. 33.3
I've not seen a Tissot marked where the OP example is numbered. Tissot 33.3-41 movements were typically marked down by the balance wheel, as seen in this example: However, Tissot usually printed its serial number on the inside caseback on chronographs during this time period. I've not been able to determine if the movement numbers were issued by Tissot or Lemania.
I think the bridge with the low number derives from a Lemania movement. Please find attached this picture which shows a similar low number on an original Lemania "33.3 - equivalent" I think this is the solution to the question of the OP
