This may have been the most popular "generic" Swiss
dive watch case from the 1960s. In addition to
Wittnauer it was also used by Breitling, Aquastar, and
many others. I've seen this watch on ebay with more
different manufacturers names than I can remember.
Although common, it is a solidly built case with nice
proportions. This example has no depth rating (due to
the crown design), but I have seen others with depth
ratings up to 60 ATM/999 feet. The slim proportions of
the bezel allow the use of a large dial on what most
would consider a small case. This is a nice example
of early '60s style.
Trendsetter: In 1965 Seiko introduced their first dive
watch, the model 62MAS, now much coveted by
collectors. This original Seiko diver is a near
duplicate of this popular Swiss design.
