You know how most diverís watches far from resemble anything like the diving instruments that they purport to be.

They tell the time and date, they look pretty on our wrists; some can even be used for measuring elapsed dive-time.

Hereís an innovative new dive watch that does all the above and more; oh, and it looks like proper diving-instrument to boot.

Introducing the new Hydrosphere from Reservoir; faithful to the technical demands of dive watches, it offers a fresh new perspective on dive-time with a dial that has a single needle.

The Hydrosphere comes with an operation indicator at the base of the needle and a disc that turns with each second that passes.

Inspired by a Scuba diverís pressure-gauges, the Hydrosphereís satin-finished, 45mm, 316L Stainless Steel case is equipped with a unidirectional, rotational diverís bezel and a Helium Escape Valve.

The bezel has a ceramic inlay that comes with a double scale. The purpose of the dual scales is to allow the diver to read dive-time at different diving depths (before and after the retrograde minute handís return).

In addition to the special bezel and HEV, the Hydrosphere has a screw-down case-back and crown, an AR-treated Sapphire crystal, and is water-resistant to 250 meters.

Powering the watch is a self-winding mechanical movement with 37 hours of power-reserve. Its complications include:

retrograde minutes, jump hour, power-reserve indicator, date and a patented proprietary 124-pieces module on its ETA 2824-2 caliber.

The Hydrosphere comes on 316L Stainless steel bracelet that is screwed to the main-case. It has a brushed finish with a bladed folding clasp and a diverís extension system.

There are three versions of the Hydrosphere: the Black Fin, the Blue Hole and the Air Gauge (white). It has a price of 4300USD plus taxes.

Thoughts? This is such cool dive watch (complicated looking but cool); while it should appeal greatly to the technically-minded scuba diver;

it will likely leave the rest of us latent and wannabe scuba divers scratching our heads!
