Lots of people ask about dating watches so I thought it might be a good idea to share our collective information. I'll start the ball rolling with dating Omegas. Essentially all Omegas are dated by their movement number, obviously you'll need access the movement to find this. Once that's done here's a list of movement numbers with corresponding years, I hope this is legible. Although this is a good system and extremely useful it's not infallible or 100% accurate. Lots of Omegas are put togethers or frankenwatches especially the more iconic models. For example a vintage SM300 may well have a cal.

Assume an eight figure number, first four are 2014, this is the catalogue model number, and to the right, 2468 indicating a 24 movement, and year of manufacture as 1968. As far as is known, longer than eight figure numbers follow this pattern, but always with the last two indicating year of manufacture. I'll stand to be corrected in the last part of that statement if anyone knows better or more - and watches made in other Timex plants worldwide may not follow this set of rules exactly Timex sub-brands also using some or all of this system include Kelton, Saga and various unbranded character watches.
