These Tissot T12 Chronograph watches are really undervalued in my opinion. This TISSOT SeaStar T12 is a massive watch measuring 42mm. across x 49.5mm. lug to lug and 13.5mm. thick and retains the original TISSOT winding crown. This is a compression case back. The pristine black dial is quite exotic and original, with red accented original chrono hands and original white pencil hours and minutes. There are red accents at the 5 minute markers and large steel markers. The large case sparkles with embossed ship logo on the rear. The very fine manual winding Lemania 1281 chronograph movement gleams as well-just meticulously cleaned and all functions operating smoothly and accurately. This watch truly looks new for its 1970’s age. This is one of the best examples of this stunning chronograph you will find anywhere!
