Hello watchex, Carch and release for me, the incredible Doxa Sub 300T Aquamarine. I bought this from a watch dealer on here with a storefront, and negotiated down to $1350. Selling to you what I paid, and I’ll cover shipping. It’s an incredible watch and the water resistance to thinness is unheard of, more than twice the water resistance of the Sinn U50 but marginally thicker. The finishing on this watch is very dynamic, the dial has a shimmering texture and the hands are a high polished gloss black. It can definitely play as a GADA watch with the elegant mesh bracelet. The watranty card is dated 09/2023 and the watch is a full kit. Running excellent. $1350 shipped CONUS net to me (Zelle is preferred). No trades. Thank you.

Doxa, founded in 1889 by Georges Ducommun, began as a maker of dress watches and other timepieces. Over the years, Doxa gained in size and branched out into other timekeeping markets. (Wristwatches, Armbanduhren, Montres-bracelets; Brunner, Gisbert L; Pfeiffer-Belli, Christian; Koneman, 2006)

In the late 1960s Doxa decided to devote resources to create a watch to be used for diving. Tests indicated that an orange face was more visible in murky water. Doxa also consulted with divers, including Jacques Cousteau, then chairman of "U.S. Divers," and Claude Wesly (a Cousteau companion and the first man to spend seven days thirty-three feet underwater). A staff of engineers and professional divers was assembled to create a watch with the required features. The Sub300t was purchased in quantity by U.S. Divers, who resold the watch in the United States.

The Jenny family of Switzerland now owns the brand. Since August 2002, Doxa has introduced re-editions of its watches and timepieces in limited quantities. Many are reproductions of the original models in design and construction, and all use Swiss movements.
