Buying Guide Extreme Deep Dive Watches

Dive watches are some of the most beloved and popular timepieces. In the 1960s, the military and professional diving requirements, together with the growing popularity of scuba diving, made the importance of trustworthy subaquatic instruments paramount. The first modern dive watches were born to monitor dive times in the briny depths. The hardiest of them can withstand the pressure at the bottom of the Marianas Trench (even though we are talking concept watches here). Their depth rating by far exceeds your most extreme needs, but there is something fascinating about their extreme engineering. And a rugged dive watch has always been a symbol of the adventurer in us all. Here are six dive watches that can fathom depths of 1000m and beyond released in the past few years.

Note: Naturally, this is a non-exhaustive list so do not hesitate to mention your favourite members in this category!

Rolex Deepsea ref. 126660

The extreme-depth Rolex received a facelift at Baselworld 2018. The essence of this professional diver has been kept but, the new Ref. 126660 brings discreet but worthy updates to make it better on the wrist and up-to-date mechanically. The case is still capable of withstanding pressure up to 3,900m but the lugs are thinner and the bracelet 1mm larger. Inside is the latest generation calibre 3235 with a new escapement and a 70h power reserve. It is COSC certified as well as being internally certified, as a superlative chronometer – with -2 to +2 seconds a day.

  1. That is very narrow minded Frank, especially with an article about a tool watches like this.

  2. An exclusive focus on mechanical is what sets MONOCHROME apart from all other watch publications. Our passion for watches sprouts from the beauty of mechanics.

  3. Ignoring quartz watches is very ill-advised.

  4. @todd absolutely, the watch was one of the deepsest divers when launched, it has been discontinued for a few years though.
