It looks like someone might have accidentally added one too many zeros to this watch’s stated water-resistance. Nope that’s not a typo, folks – this leviathan of the deep is a new model from water-resistance prodigy, H2O Watch of Germany. Based on that little known diver made for OceanicTime, the 10 MILES, this is the new Kalmar Deep Diver. 

Yes, the name is a bit of a cliché, it is also a gross understatement as this watch has been tested and officially certified by a leading German institute to withstand a pressure of more than 2500bar AKA 25’000 meters. Just to put that into perspective, the Challenger Deep, located at the southern end of the Mariana Trench, is the deepest spot in the ocean; it is 11’034 meters deep, so this watch has a depth rating of more than double that. Perhaps it might be better suited for a dive in (Jupiter’s largest moon) Europa’s ocean which has an estimated depth of 40 to 100 miles (60 to 150 kilometers). Nevertheless this is serious overkill but when did that ever do anyone any harm.

Now that you picked your jaw back up off of the floor, you’re probably wondering A.) why? and 2.) how is this even possible? For the answers to those important questions I kindly refer you to the 10 Miles article published 11-30-2018.

You’re probably also assuming that any watch engineered with this level of water-resistance is most likely unwearable. You couldn’t be more wrong. The watch’ case is made from lightweight Titanium the dimensions of which include a diameter of 42.5mm and a case height of 22.85mm. The Kalmar Deep Diver comes with a slew of special aesthetic and technical features such as its graduated Sunburst dial which fades from inky blue to black or is it black to blue. This is with beautiful 3D appliqué indexes along with H2O’s signature “merry go round” handset.

Btw the dial does absolutely nothing to shout about the watch’s monumental level of water-resistance however there is stark reminder laser-etched into the watch’s custom rubber diver’s strap which bears the “DEEP DIVER” name along with “25000M”. There is also a discreet lug engraving with ‘’25300M CERTIFIED’’ its officially certified depth rating.

Housed inside the Regular Version of the Kalmar Deep diver’s almost indestructible solid Titanium Grade 5 case is a Swiss made mechanical automatic movement, the Selitta SW300 with a beat-rate of 28.800 vibrations per hour; 4 Hz. Inside The UN-Limited version is the Upgraded Swiss ETA 2892 Automatic Movement!

This is a far more practical and functional version of the TEN MILES thanks to its minute track and of course the proper diver’s bezel complete with dive-time scale. Even without its absurd (let’s not be coy) depth-rating, it is such a lovely tool diver – top marks all round!

Absolutely Awesome! Near impossible to find and unable to be ordered! This is The UN-Limited Special Edition featuring the upgraded Swiss ETA 2892 movement, The upgraded 10.25mm Crystal & the additional Brand New H2O Black rubber strap with Black Steel Deployment buckle!
