Up for sale, from my personal collection, is this vintage Doxa SUB300T Searambler.

The case is unpolished and has signs of wear compatible with the use and age of the watch, the original brushed factory finish is still present and well visible.

The dial has a cool patina and spotting, it becomes more or less pronounced if you tilt it in various angles as you can see in the photos.
The tritium on the indices and hands has turned in a dark amber colour.

Expandro supplied bracelets to Doxa, the one included in the sale is not original to the watch and it has straight end links but with the same expansion system that made these bracelets famous.

The tropic strap visible in one photo is not included.

Last service date is unknown, the movement is in working conditions, winds smoothly and runs well.

I'm asking 1750€ including shipping in the EU only, the watch is located in Italy, i'm obviously happy to answer any further question and provide additional photos.
Many references available.

	Established:	1889
	Website:	https://www.doxa.ch/
	Country of Origin:	Switzerland

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.
