A large men’s vintage Mirexal SuperAutomatic divers watch, with vivid blue dial, complete with original box.  Model reference C 757 432.


The movement in this watch was made between 1969 and 1976.  Given the styling of this watch is more late 1960’s than mid 1970’s we think this watch was made circa 1970.  (NB The brand Mirexal wasn’t registered until 1988, but this watch was clearly made much earlier.)


Mirexal is not a name most people have heard of outside of Switzerland.  It was the house brand for the supermarket chain Migros for a while, and you can read a little more about them here.  Safe to say if you are a large Swiss company selling watches in Switzerland they had better be good, as your customers are the most informed on horology in the world!  So they didn’t cut corners.  The ETA 2783 automatic is good quality, the case is very solid stainless steel, and the crown is screw down.  The bezel doesn’t click and can turn either way, so it wouldn’t meet modern ISO divers standards, but this is a vintage diver and that is all about the looks for 99.9% of people.  The blue dial is surrounded by a black ring that holds the applied markers.  The white hands are very good, and the lume at the hand tip ends is surrounded by orange paint (which the second hand compliments).  This all makes for a very easy to read watch.  The bezel has lost most of the paint for the numbers.  The bracelet appears to be original when compared to the few other SuperAutomatics we could find, but is not stamped with a maker.  The bracelet has been cleaned in our ultrasonic bath.  The box has a little damage, but is a rare survivor.

This watch will be supplied with the original branded presentation box and our Certificate of Authenticity.
