HOW DO WE DATE THIS WATCH?

From the serial number on the case back we can accurately date this watch to being made in January 1986.  The guarantee paperwork, and the original till receipt, are both dated and show it was sold in June 1986.

CONDITION

The 7A** series of movements are always popular with collectors.  The movements were the world’s first analogue 1/10th second quartz chronograph, and they were also features in various classic eighties films.  Even James Bond had one!  Plus they are fully serviceable, where a lot of eighties quartz watches were made to be disposable.  The 7A28 was the chronograph, the 7A38 added a day and date complication and the top of the range 7A48 like we have here lost the day of the week function but gained the moonphase.  Quartz is an ideal match for a moonphase complication, as even if you don’t wear the watch for a few days the moonphase is still correct (whereas a mechanical watch would need resetting).  Everything is working correctly, and we will install a brand new battery before sending the watch out to the new owner. The gold plated highlights are looking good.  The original bracelet, code B1406, is quite long and our sister website, SpareLinks.com, may have extra links if required.  The bracelet has been cleaned in our ultrasonic bath.  The inner rehaut is not quite lined up in the photos, but this has since been amended as shown in the video.

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