Hello,
I would greatly appreciate figuring out the year this watch was made. I recently purchased this Richeville as new old stock. It has the older, rectangular stepped steel case, guilloche silvered dial, automatic movement, the serial number on the hang tag is 25200.0.11.151, the back of the case reads Richeville A, No (as in number) 304, ref 2520. I know the watch was made in the late 90s and possibly up to 2001 but pinpointing the year of production is my objective.
Sincerely,
James
