This watch is awesome! It can be dressed up with a lizard/gator strap or it can be very casual, as shown with the current strap. This is a 1954 Tissot. Although, it may be a late run 1953 model based on which serial database is used.
The case measures 37mm without the crown, has a thickness of 10.5mm, and a lug width of 18.5mm (I know, but that is my best measurement).
That said I have had both 18mm and 19mm straps that fit perfectly on this watch (not all straps are dead on the number either). For context, I have included wrist shots of my 7.25" wrist. I believe that the case and crown are original and haven't been over polished.
The case shape might give the illusion that is has been polished down. However, to provide context, I will include some photos of other Tissot models in the same case.
The original dial and hands are what made this piece stand out to me.
Shame, shame...Tissot was still using Radium in 1954, twenty years after some of the "Radium Girls" had died. It has a rose gold colored applied logo and indices with lume plots tucked behind them. Neither the fluted alpha hands nor the dial are missing any radium paint. The silver dial has aged to an even, light champagne color and features a radium burn from a sedentary hand, pointing to about 10:45.
The layout and case shape remind me of the Omega Seamasters from the same era or the reissued Omega 1948 Limited Editions.
The bad news...The crystal looks good but there are two noticeable marks. One is near 5 o'clock that actually cast a shadow on the dial in a few of the photos. The other is a scratch in between the 7 and 8 o'clock indices. It most likely will need a service as it runs about a minute and a half slow in a 24 hour period. And last, there are two small scratches on the actual dial. One near the four o'clock marker and another to the right of the 3.
I am asking for $750. I will cover all fees and shipping charges to ship it within the Continental United States. Thanks for looking!
And here are three examples of other Tissot models in the same case (pics borrowed from the internet)...
