The Comet was a short lived watch from normally a very conservative manufacturer.  Two revolving discs tell the time, set on a conventional movement.  Model number 8475.


From the serial number on the case back we can date this watch to being in 1970.  We have asked Longines to confirm this.


UPDATE:  We have managed to source a NOS crystal, which is being fitted now.  Photos, videos and description will be updated in due course

The Comet models didn’t sell well when new, but that just makes them more collectible now.  They were available in various colours, with Blue, Yellow and Red being most popular.  Towards the end of production they also appeared with hands and a normal dial, presumably to use up the unsold cases and movements.  The ones with hands are worth much less than the disc versions now though.  There is more information on the Comet model on this website, albeit from 2011.

The video shows how the large hour hand and the minute hand dot move.  Both of these are covered in Tritium lume, and the dot has faded more than the hour marker which has turned a nice cream.  This seems to be consistent with other examples we have seen.  This watch will be going for a service now, and we hope to clean off some dirt on the minute track too.  The acrylic crystal has been polished – the wording is printed on the inside of the crystal so no danger of rubbing it off or scratching it.  Inside the stainless steel case is a Longines calibre 702 17 jewel movement.  The blue leather strap with contrast stitching is new.  The signed crown is original, and the case is unpolished

This watch will be supplied with our Certificate of Authenticity.
