Oris Aquis Date 43.5mm – Green Dial, Stainless Steel Bracelet | Ref. 01 733 7730 4135-07 8 24 05PEB

History

Even though the Oris Aquis collection was launched in 2011 it has its roots embedded in the first diving watch by Oris in 1965. Since the launch of the collection, the Aquis has since various iterations such as the GMT and the Depth Gauge.

Features

Being a diving watch, the Oris Aquis collection is equipped with a uni-directional rotating bezel with a ceramic insert and protected crown. Made with sturdy case materials such as stainless, titanium and DLC coated titanium, the Aquis collection offers robust performance even at depths of 300 metres and in some cases up to 500 metres. In most of the series such as the Aquis Date Calibre 400, Aquis Date, and Aquis Depth Gauge, the date window is fixed at the 6 o’clock marker. Whereas, the only exception is the Aquis GMT Date where the date window is fixed at the 6 o’clock marker.

The Aquis Depth Gauge

Oris has a reputation for creating well-built timepieces. One such timepiece colludes with the qualitative personality of the brand and the innovative persona. The series of timepieces is called the Oris Aquis Depth Gauge. Being one of the few mechanical watches that offer a real-time depth gauge on the dial, the Aquis Depth Gauge is also known as the ‘watch with a hole’. The depth inside the watch is measured by the Boyle-Mariotte Law. A law that defines that the combination of pressure and volume remains constant. This is calculated by a channel inside the watch marked by a hole at the 12 o’clock marker. The channel is filled with air on the surface and when the wearer dives inside the water body, it is filled with water. As the channel is getting filled with water, the air inside the channel gets pressurised. This pressure is then depicted by a counter under the index markers. This integrated depth gauge makes the Oris Aquis Depth Gauge a robust tool for divers.

Limited Editions

The Oris Aquis collection is home to various limited edition timepieces such as the Dat Watt edition, the Sun Wukong artist edition, and the New York Harbor limited edition. The Dat Watt limited edition is a unique rendition of the moon phase complication. Instead of a pictorial representation, the Oris Aquis Dat Watt displays the moon phases in the northern hemisphere through a small arrow hand. Apart from the Dat Watt, the Sun Wukong Artist Edition features a hand-painted cloisonné dial depicting scenarios from the movie 1961 Chinese animated movie, the Havoc in Heaven.
