A huge chunk of a watch, with mirror dial and original bracelet.  Omega’s first in house developed megaquartz watch.  Model reference 396.0817


From the serial number on the movement we can accurately date this watch to being made in 1973.  This was the first year of the 1310 calibre production, and a year before this model was officially available according to Omega’s own website.  So this could have been made ready for the launch.


This is a bold watch.  Not only is the size quite big, even by modern standards, but the gold plated case and bracelet make it stand out even more.  Square watches take up more wrist area than round ones, so although the width is 40mm it does wear larger than that.  The bracelet construction is unusual – it seems to be a billet of stainless steel wrapped in gold or gold plate.  Importantly the bracelet is long enough for most wrists.  That Megaquartz 1310 movement was Omega’s first quartz movement they developed, but they did have the 1300 calibre before which was their version of the Beta21.  We have found a copy of the instructions for this movement, and everything is working well – this included the pushers to advance the date and second hand, as shown in the video.  Sometimes on these watches these pushers can become sticky because they are not used or have not been cleaned, but this example is good.  The dial is smoke mirrored, which is really difficult to photograph and the video is a better example of how this changes dependent on what is being reflected.  The glass does have a few scratches, but not bad enough to ask Omega to fit a new one (they restrict the parts to their own service centres).  However the scratches in the glass are reflected on the dial, so you may want to source a new crystal.  As quartz watches, especially quartz watches that were in the early development of quartz become more collectible this watch is only getting rarer to find and costlier to buy.

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