Doxa Sub 300T Professional Divers Wrist Watch circa 1970’s Original Orange Dial in excellent condition with black & luminous markers, date aperture Automatic movement signed Synchron Stainless steel Tonneau shaped case with rotating bezel signed Synchron SA, Doxa logo embossed, numbered, original crown Case width approx. 42mm New Stainless steel bracelet Markings on case back: 719516 Syncron sign 58098 – 59 33110 Very good condition with minor traces of wear, case has very small nick at 25 past approx., please study photos Fully functional and keeping excellent time Please note that this watch is a rare and original Divers Watch from the 1970’s.  It is all original and has not been polished (if at all) to within an inch of its life, or otherwise tarted up. Fortunately it has not had a hard life as many divers do, so it is presented in a very attractive overall condition. It is powered by ETA movement Cal 2783 in very good condition and performing fine.  All functions work – there are no issues (other than mentioned here) of which I am aware. I am re-balancing my collection and the Doxa is for sale after a few years of ownership but hardly any wear time.  I purchased from a Watches of Knightsbridge auction so I really do not think there are any doubts as to the authenticity of the watch.   Serious offers invited and any questions, please ask.
