This high beat, high specification men’s Zodiac SST has a day and date calendar complication and an unusual oval case.

HOW DO WE DATE THIS WATCH?

There are no serial number databases for Zodiac watches that we know about (the serial number is between the bottom lugs), so we have to do a little more detective work.  The trademark Zodiac SST was registered in September 1969, and the movement used in this watch is credited to first being used in 1970.  Given these factors, and the lack of any other firm dating evidence, we think the watch was made circa 1970.  That perfectly fits the styling and technology used too – High beat movements were a late sixties and early seventies phase, before the widespread cost cutting of the 1970’s kicked in.

CONDITION

Calibre 86 was designed by Zodiac and was a high end movement.  The watch can be wound automatically or manually, has quick set date and a day window, ticks at twice the standard speed (so this ticks 10 times a second) and at the time it was guaranteed to be within a minute a month on the timing – that is an impressive +2/-2 seconds per day.  Calibre 86 was also used in some other Zodiac watches, including some of the Astrographic models (albeit slightly modified to hold the transparent discs that model uses instead of hands).  The acrylic crystal does have some light fissures, which you might see at certain angles.  The stainless steel case does have some scratches on the wide bezel, which you often see the watches this shape (such as the Omega Dynamic).  The dial is very good, and we have taken a photo of the watch without the crystal to show just how nice it is.  The grey suede strap is new, and could be swapped for a different colour if preferred.

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