Hi, everyone! I'm new to this forum and generally new when it comes to collecting watches. I recently picked up what I believe to be a Tag Heuer 2000 series mid-sized 2-tone watch. From what I can see (pictures attached) the reference I believe is 665.013 and the serial code is JO9741. I've done a bit of research online and the model year seems to range between 1990-1999. Is there any way that I would be able to identify the exact year? From my limited understanding and Google searches, Tag Heuer changed their serial coding in 1992 from the 2 letters + 4 numbers system. Does this narrow the year down to 1990-1992, or am I just making silly inferences? Would love to get some thoughts and opinions. Thanks!
