...back-set, with the crown on the back? If so, it's likely that the number you are looking for is way on top of the dial - above the 12. You should be able to se a number there. Since you have that ( rare ) 14K gold case, there's propably a small crown symbol over "TIMEX" on the dial. If that is the case then your watch has the catalog number: 9064, with the movement number 84 and is from either 1966, 67 or 68 ( i.e. 90648467 ). If you don't see any numbers you have to take the crystal off. Looks like the watch came with a lizardgrain leather band. Hope this helps. WELCOME!
