Tissot 1963 Seastar Calendar Automatic
You can see the distinct aesthetic of modern Tissot watches start to take shape already in this Seastar from the early 1960s, although the contrasting gold hands/indices and steel case is definitely a classic look. One oddity about this watch is that the Tissot 784 movement has no quickset at all for the calendar - not even a unidirectional calendar driving wheel - so setting the date can be a pain. I usually don’t bother when I wear this one.
