Oris Aquis Depth Gauge
Via Monochrome:
"In their press release Oris states they have produced the first divers watch which measures depth by allowing water to enter the timepiece. Actually the first watch that allowed water to come into the case, in order to measure diving depths, was the IWC Deep One. Of course the water ran into a tube and didn’t stream between the gears and pinions. Oris’s construction is different, more simple, but very effective.
Oris’ engineers have applied the Boyle Mariotte Law to the patented Oris Aquis Depth Gauge. The special sapphire crystal is 50% thicker than an average top glass and features a channel milled into the side. This channel runs anti-clockwise round the dial, stopping between one and two o’clock. At 12 o’clock, a inlet leads to this channel. The join between the crystal and the case is sealed by a rubber gasket.
On descent, the air inside the channel is compressed by the surrounding water pressure, allowing water to enter through the inlet at 12 o’clock. The transition between light grey and dark grey, marks the depth. It differentiates between water and compressed air on the scale around the outside of the dial, indicating depth while descending or ascending.
This means it will only indicate the actual dive depth and does not have a hand to indicate the deepest depth reached during a dive. On the other hand, this indicator benefits from no inertia, not delaying the accurate and actual depth indication, which is particularly useful in decompression breaks in lesser depths!"
•Ref. No. 733 7675 4154 Set, Ø 46.00mm
•Automatic Oris movement 733 with date window at 6 o’clock
•Stainless steel case, water-resistant to 50 bar/500 metres
•Unidirectional revolving top ring with black ceramic inlay and minute scale
•Sapphire crystal, domed and antireflection coated on both sides, features a milled channel for depth gauging and a yellow metre scale
•Rubber strap and metal bracelet as alternative
•Set includes waterproof case, separate metal bracelet and tools
•Retail Price CHF 3,500 or € 2.600
