Doxa Sub 600T Watch Review: Design and Performance

The Doxa Sub 600T is an automatic Swiss-made dive watch with a 40mm stainless steel case, a unidirectional rotating bezel, and 60 bar (600 meters) water resistance. It rekindles the angularity that characterized DOXA in the 1980s, and they call it the smallest-diameter watch in its line.

This review is based on the design and performance of the Doxa Sub 600T, using specifications released by DOXA and LaViano Jewelers, not actual testing. It also compares the model with the Doxa Sub 300 and provides examples from LaViano Jewelers' DOXA collection, such as the Doxa Army Bronze Bezel.

Design: A Modern Take on an Eighties Icon

The Doxa Sub 600T retains the appearance that made the original popular. The crown is positioned at 4 o’clock, and the case retains the angularity that differentiates the 1980s model from the previous rounded designs of DOXA. It is the smallest in the family at 40mm, but DOXA says the dial appears much larger than the case. DOXA offers the bezel with a sandblasted steel insert or a black ceramic insert, in six emblematic colors. The watch comes on a tone-on-tone NATO strap or a new 316L stainless steel bracelet that adds a “modern vintage” touch.

Performance: Water Resistance and Bezel, Movement

The LaViano table of the Doxa Sub 600T indicates an automatic movement with a 38-hour power reserve and a frequency of 28,800 vph (4.0 Hz). It shows hours, minutes, seconds, and date, and the case has a screw-down crown. DOXA claims that the 316L stainless steel case has a sapphire crystal on the top and is pressure-resistant to 60 bar, or 600 meters, which is more than enough even for ambitious divers. The patented unidirectional bezel displays the time in minutes and the diver's depth in feet, allowing a diver to determine a safe ascent without decompression stops.

Doxa Sub 600T vs Doxa Sub 300

LaViano lists the Sub 300 with a 42.5 mm 316L stainless steel case, a COSC-certified chronometer movement, a 38-hour power reserve and 300 meters (about 980 feet) of water resistance. It has a domed sapphire crystal that is treated with an anti-reflective surface, and the dive markings are written in Super-LumiNova to be read in low-light conditions. The Doxa Sub 600T is twice the depth rating and has a smaller 40mm case, whereas the Doxa Sub 300 is chronometer-certified and has a bigger presence. The right choice depends on your wrist size and how important each feature is to you.
