Introducing Aquis Depth Gauge
A first ever watch that let's water inside to measure the depth of the ocean.
THE LAW OF PHYSICS WHICH INSPIREd ORIS’ INVENTION
Robert Boyle (1627 – 1691) was a leading intellectual figure of the 17th century and one of the founders of modern chemistry. He was the first prominent scientist to perform controlled experiments and publish his work with details concerning procedure, apparatus and observations. He began to publish in 1659 and continued to do so for the rest of his life.
WHAT IS BOYLE'S LAW?
It is Boyle's Law for which he is most famous and which states that if the volume of a gas is decreased, the pressure increases proportionally. Since this principle was independently discovered by the French Edme Mariotte (1620 – 1684) the law was named after both scientists.
The Oris Invention ®
Oris product engineers were the first to apply the Boyle-Mariotte Law into the top crystal of a watch by milling a small channel into the side of a sapphire crystal. The channel runs anticlockwise round the sapphire glass, stopping between one and two o'clock. At 12 o'clock, an inlet leads to this channel. The special sapphire crystal is about 50% thicker than an average watch top crystal, domed and anti-reflection coated on both sides. Oris patented this invention in 2012.
The Case Construction
Oris used a proven diver case from the Aquis collection and combined it with the newly invented sapphire crystal. The join between the crystal and the case is sealed by a Zytel® gasket (shown in yellow). Despite the milled channel (shown in blue) the Oris Aquis Depth Gauge is water-resistant to 50 bar/500m, thus providing the highest protection to the mechanical movement with automatic winding.
FUNCTIONALITY OF the DEPTH GAUGE
When descending with the Oris Aquis Depth Gauge, water enters into the milled channel through the inlet at 12 o’clock of the sapphire crystal. The increasing water pressure compresses the air inside the channel. The water causes the color of the channel to become dark grey. The edge between dark grey (water) and light grey (compressed air) marks the depth on the yellow metre scale on the inside of the sapphire crystal. For enhanced readability the sapphire crystal has a non-reflective treatement on both sides.
THE TIME INSTRUMENT
The new Oris Aquis Depth Gauge is a compact high quality timing and depth measuring instrument. The black ceramic inlay of the unidirectional revolving top ring has an engraved 60 minute scale, with individual minute lines from zero to fifteen. The white Super-LumiNova® applied to the hands and indices, gives not only excellent visibility underwater but also one of the longest lasting luminosities of all Super-LumiNova® colours. The high contrast yellow metre scale printed on the inside of the sapphire crystal emphasises the well-balanced technical look.
THE REVOLUTION IN THE WORLD OF DIVER'S WATCHES
Innovative Clasp with 'Sliding Sledge'
The clasp for the rubber strap version has a 'sliding sledge' that allows rapid adjustments to be made without opening the clasp.
Conversion Scale on the Case back
The stainless case back of the watch features a specially engraved metres to feet conversion scale assisting divers with rapid calculations.
Unique "Anchor" Design on the Strap
A specially designed rubber strap with an "anchor" shape supports the watch with additional safety, preventing it from falling off.
The Oris Aquis Depth Gauge, An all-in-one Set.
The packaging of the Depth Gauge perfectly complements the character of the watch. To begin with, the case is waterproof – an apt presentation for a divers watch of such calibre. Housed within the case is a replacement metal bracelet, a set of tools to change the strap and a certificate that contains details on the Oris Depth Gauge. To complete the set, the brand has also included a specially configured sapphire crystal cleaning device for diving enthusiasts.
