Astute watch collectors keep an eye open for authentic variations on the standard specifications for the models they collect. There's a simple reason for this. Rarer or more usual examples add depth to a collection and often represent a very good investment proposition.
Here's an authentic variation on standard Constellation dial livery that is most uncommon. While I have seen calibre 551 models with applied numerals on each hour surface from time to time, this is the first instance Ive seen such a variation on later Constellation models.
The model above is a case 168.005 powered by a calibre 564 movement with the serial number dating it to around 1967. It is in superb original condition: case, dial and movement are pristine.
The watch was picked up at a jewelery auction in Melbourne a couple of months ago for the US dollar equivalent of around $520.00, making it an exceptionally good buy.
My thanks to Ken for sharing his pics of this interesting find.
