I recently acquired these two 165.014-63 Seamaster 300s. They were manufactured exactly 5 months apart, and both look like honest and untouched examples. You will note that (condition aside) they are pretty similar in appearance, right down to the Green hour & minute hands which are 100% original Tritium and original to both examples. The example on the right is the earlier of the two. July 9th 1964 production date. Notice the "SWISS MADE" only dial. (No T's). Movement is Cal 550. The example on the left is the later of the two. November 9th 1964 production date. Notice the T SWISS MADE T dial where the Ts are in a lighter color which means that Omega added the T print to the dial at a later point. I bought the mint condition example about a month ago from the original owner's family in South America. Before I received the watch, and just going by the pictures I was sent from the sellers, I was certain that the hands were changed to service hands at some point. However, upon receipt & in hand inspection of the watch, the hands checked out to be 100% original Tritium and it was clear that this is a true untouched piece in stunning condition. The best one I have ever seen. The other example was purchased a couple of weeks ago, and as you can see it sports the same Greenish hands. And after some Polywatch... And here is a 3rd example (not mine) of a 1964 165.014-63 that I found for sale online. Notice it has the same Greenish hands and also looks to be an honest and untouched example. It is interesting to see the similarities and minor differences between examples of the same reference made only a few months apart. According to the production dates, it is apparent that Omega added the T print to the dials between the 3rd and 4th quarter of 1964.
