Overview
A robust Swiss-made automatic wristwatch featuring a stainless steel case with a decagonal screw-down back and a distinctive 'galleon' relief. The 'Visodate' designation highlights its integrated date window, while the 'T.12' signifies its advanced water resistance for the era.
Story
The 'T.12' on the dial isn't just a model number; it's a boast. In an era when most watches feared a splash, this was rated for 12 atmospheres of pressure—roughly 120 meters deep. The galleon on the back symbolizes Tissot's 'Navigator' spirit, built for those who explored both land and sea.
Maker / Origin
Founded in 1853, Tissot merged with Omega in 1930 to form the SSIH group, leading to decades of shared technical innovation. During the 1960s, Tissot was the 'cool younger sibling' to Omega, producing high-quality, avant-garde designs that utilized many of the same movement architectures as their more expensive counterparts.
Condition & Value
The dial shows some light 'patina' or spotting consistent with age, and the case has expected surface scratches. The crown appears original, which is a plus. The leather strap is a modern replacement. Overall good vintage condition; a professional service would likely increase the high-end value.
