I find a vintage watch which holds such aesthtic appeal to me, that I acquire it without any concerns about the quality of the movement. This Tissot is a perfect example. It's an automatic from the early 1960's, with a cal. 28.5R-21 movement. The 17 jewel movement, which was also found in many of the Seastar models, is bi-directional, has a nickel screw balance, Nivarox hairspring, and Incabloc shock resistance. There's certainly nothing wrong with the movement, and it functions well, but it is unexceptional. That's OK with me, though, as I really like both the dial and case design.
The dial, showing one of my favorite, simple configurations, is beautifully balanced, and the classic, applied Tissot logo has long struck me as one of the most attractive of that era. The 35mm screwback case is perfectly suited to the watch, and the use of a partially recessed crown completes the understated, functional design.
