This week Doxa announced an entire collection of serial production Sub 300 dive watches.

Instead of restricting customers to limited editions, as they have done for the past three years (here, here, and here), Doxa now offers the Sub 300 in a full array of six dial colors — with an option for a strap or bracelet for each.

The dial colors are Orange Professional, Silver Searambler, Black Sharkhunter, Navy Caribbean, Yellow Divingstar, and Turquoise Aquamarine. The Professional Orange dial is the most famous of the Sub 300 line but according to Doxa in 1967 the watch came in all six of the newly released colors.

The 42.5 mm stainless steel case is the same size and shape as before, although the thickness has been increased to 13.40 mm. Interlug width is 20 mm and lug-to-lug the watch measures 45 mm.

As with other contemporary Sub 300 models, the COSC-certified ETA 2824-2 automatic movement with 25 jewels that beats at 4Hz and has a 42-hour power reserve drives the hours, minutes, center seconds, and date. The COSC version of the ETA is the top-of-the-line and is finished to a higher specification than standard and elaborate versions of the popular off-the-shelf movement.

The unidirectional bezel with dual markings for dive times and depths for calculating and monitoring no-decompression dives remains the same. This enables divers to first determine and then monitor the time they could remain at a predetermined depth and still ensure a safe return to the surface — without having to make a decompression stop on the way back up. There are two separate scales on the bezel, one orange for the outer “depth” ring and the other black for the inner “time” ring — and this is patented by Doxa.

As always, the domed sapphire crystal, screw-down crown, screw-in caseback, and multiple gaskets ensure the 300-meter depth rating for which the Sub 300 is named.

The main difference between these new production Sub 300 models is there are no special emblems on the dials, as was the case on the Black Lung model or Divingstar Poseidon — and the one millimeter thicker case.

Retail is $2,450 on a rubber strap and $2,490 with the stainless steel beads-of-rice bracelet.
