1975 DOXA [Swiss] Sub 300 T “Professional” Aqualung Diver Watch – ETA Cal. 2783


Out of stock

From 1975 a classic ‘Professional’ SUB 300T diver from DOXA’s [Swiss] Synchron era for U.S. Divers Aqualung, that has been professionally restored and fully serviced by Localtime.

The large C-Type stainless steel case is in excellent condition, houses an ETA Cal. 2783 with date and measures in at 42mm or 45mm including the crown at 3h. The signature orange dial, set of 3 hands and bezel are in great condition. The original owner bought it in 1975 and had it serviced in 1988. As the original owner told me, during the 1988 service, the watch received a new glass [now has some scratches on it], a new bezel and a lume touch-up. It is wearing a brand new black soft rubber strap with orange stitching that accentuates the watch pretty nicely. I have included many photos of the watch, a snapshot from the restoration but also some closeup snapshots I took just for fun and to allow you to enjoy the lovely details of this fine timepiece.

The last photo shows some of the DOXAs I usually have on display in my store and it is for presentation purposes only. As with all the watches that are serviced by Localtime, the BIN price includes a written 3-month written warrantee from the date of purchase. Feel free to contact me for whatever questions you might have.

EXTRA! Check out my own Localtime straps: Handmade from premium calf leather to my own specifications in Italy, they come in 5 sizes [lug width/buckle width]: 18/16, 19/16, 20/16, 21/18 and 22/18mm & 8 colours: tan, brown, dark brown, black, cinnamon brown, olive green, denim blue and grey blue. I sell these separately in my eBay store under eBay item number 401105271426 and you can also see them in the last photo here.
