HOW DO WE DATE THIS WATCH?
From the serial number on the case back we can accurately date this watch to being made in May 1964.
CONDITION
As the 1964 catalogue shows, these came with silver dials. 90% of the ones you see for sale will be silver dials, and the grey dial is rare. They all came on a bracelet, and they do not always survive – this one has a full length bracelet. Sometimes the bezels are missing or badly worn – again, this is as good as you are likely to find one of these. The crown and pusher are original – they both have concave ends, and the crown has flats in between the grooves – a tiny detail, but valid to point out. The case back has the Olympic flame logo – there were various case backs for these over the years, but this is the earliest. The case back engraving is feint and has worn, but is still visible. The only negative on this example is the lume plots and lume in the hands is dirty in places, but even that helps show the dial is original. The movement is all working correctly, as shown in the video, and you might go a long time before you see a better example for sale. The box came with the watch, but we can not find a reference for what box it should have had – it might be correct.

From 1st September 2021 we will be planting a tree for every watch we sell, working with the International Tree Foundation (Est 1922) to make this business positive on carbon.
