Up for sale only is my vintage Doxa Sub 300T Professional with the rare and extremely sought after "US Diver's Aqua Lung" badge.
Watch dates to 1968-1970, it's impossible to nail down the year on these vintage Doxas.
Condition is very good for a 50+ year old tool watch. The dial and hands are original and incredible. The bezel is original and was repainted where needed.
Crown and crystal were replaced when the watch was serviced in March 2024. All original parts are included as well as the service receipt. The watch is running perfect and keeping great time.
The watch will include an original Synchron branded Expandro beads of rice bracelet with on the fly adjustment which was miles ahead of its time. I'll also throw in a black tropic strap.
Asking $4699 shipped fully insured.
Not looking for trades.
Thanks for looking!
