Could anyone tell me the date of manufacture for a Le Coultre Galaxy Mystery with the serial number inside the watch case of 625-149 and on the next line 26954? I inherited it and would like to know a bit about its history. Thank you.
Pictures will help us tell a lot more about it. Most Swiss companies didn't keep accurate serial number records like the American companies did, so visual clues are the next best bet. Posting some photos of the dial, movement, and any marks on the inner surfaces of the case (including that Galaxy mark) will likely help you get some more information.
Funny that Longines came up - LeCoultre was made up of Swiss JLC movements imported to America, housed in US made cases at the Longines plant in NY.
Anyway, if the serial numbers are done by JLC then 26954 can't be correct or the watch would be from around 1932. Even is 625-149 were correct (without the hyphen) it would be 1949, and that's still too early for that watch. Either you didn't get the correct number or LC had a completely different system than JLC. The serial number that's most important should be on the movement, not the inside of the caseback.
