That rounded S was used in the 60's, and in the 60's "t" was used on lumed dials.
Check the serial number to see if this watch falls into that small overlapped period of 1961, 62?
(after looking carefully, I think it is a redial, hope I am wrong 😁)
I’ve got a couple of 165.003s, and would happily accept yours as being in original condition.
The seller says it’s 'original', in his history of ownership and the price is reasonable. The seller invites offers, so you may be able to negotiate the price slightly.
Overexposed pictures make it look whiter and cleaner than it probably is. Which is not a deal breaker, but worth asking for close up pictures in natural light.
