The Omega Equinoxe was the World’s first watch with an analogue display on one side, and an LCD display on the other.  Reference 386.0813.


The Equinoxe model was only available in 1981, so this watch has to date from then.  You can read a little more on Omega’s own website.


The calibre 1655 Instructions can be found here.  But happily we have the original booklet that will be supplied with this watch too.  That shows that the movement has the simple time only display on one side, and then wen the watch is flipped the LCD display can be used for time, countdown timer, 24 hour alarm, chronograph and and hourly signal.  All is working well, and is easy enough to use once you get the hang of it.

Stylistically the watch owes quite a bit to the Jaeger-Lecoultre Reverso, but the bracelet is also reminiscent of the Audemars Piguet Royal Oak.  If you are going to ‘borrow’ design ideas, those are fine ideas to borrow.  The bracelet is long and will fit most wrist, and has the correct clasp that still has the gold logo insert.

In the early 1980’s Omega were experimenting with making high end quartz watches like this.  Ultimately it was not the right strategy, as they had to allow swatch to buy them to save them shortly afterwards.  When new this watch retailed for 1,500CHF (about £346), when you could buy a Automatic Seamaster with day and date, on a bracelet, for £120.  This really was a premium watch.

This watch will be supplied with the original instruction book and our Certificate of Authenticity.
