Today on here on we are taking a closer look at the 2015 Oris Aquis Depth Gauge with ref. number 733 7675 4754.  An impressive diving watch, an affordable depth gauge tool watch! But first a bit of history to display the significance of Oris in the Swiss watchmaking industry.


The history of Oris begins in 1906, the year the first branch of Oris was opened. Oris’ first factory was run by only 24 workers. ORIS employed more than 300 people in Hölstein in 1911, they built houses and flats for the workers and became the largest employer in the area.  Shortly after the founder, George Christian, died in 1927 Oscar Herzog became the CEO of Oris, a position he held for the next 43 years.

Between 1946 and 1981, Oris owned ten busses which were used to transport up to 800 workers to its many factory locations. The original Oris factory founded in 1904 continuously expanded and by the 1960s Oris became one of the top ten largest watch producers in Switzerland.

Oris began producing the famous Automatic Movement cal. 645 with 25-jewel lever escapement in 1966. In 1991 the complication movement cal. 581 was developed, with moon phase display, week day, date and a second time zone.

In 1968 Oris obtained full chronometer certification from the Neuchâtel Observatory for movement cal.652.

In 1996 Oris organized the Oris London Jazz Festival this was one of Oris’ first large sponsorship events.

In 1997 Oris produced the Oris Hong Kong Commemorative Watch, to commemorate Hong Kong’s handover to China.
Oris produced a limited timepiece to represent the 100 years of watch production In 2004. Only 1904 watches were produced to resemble the date that Oris was founded, each watch is individually numbered.

In 2003 Oris signed an agreement to become the sole supplier of watches to the BMW Williams Formula One Team and  Oris is still sponsor of the Williams F1 team.

In 2009 Oris launched a limited edition watch for Bob Dylan.

Oris Aquis Depth Gauge

So today we are taking a closer look at Oris’ depth gauge, the 2015 model. Oris introduced the depth gauge in 2013 and they really succeeded well with this model. It is by far the most affordable Swiss made automatic depth gauge out there. Price around € 3.000,-! Looking at Panerai, IWC or Jaeger le Coultre, you have to spend a lot more money. And I think the Oris depth gauge is a real tool watch.

However, letting water into your watch is never a great idea, but de solution Oris provided is very well executed. They made a channel into the sapphire crystal and by the increasing pressure during diving it allows water to flow into that channel and you can read your depth on the scale around the dial. So the water flows into your crystal and not into your watch. Job well done!


The case is set to be 46mm in diameter, 50mm lug to lug (relatively short), 16mm in thickness and crafted from 316l stainless steel with a black DLC coating. It is a heavy and rather big diver, but it wears more like a 44 mm diver, very comfortable. On top a double domed 4.5mm thick sapphire crystal with AR coating on both sides. In the crystal the mentioned water channel aperture is placed at the “12”position surrounded by a undirectional bezel made of tungsten with minute scale. The screw-in and protected crown is signed Oris. The screwed case back is decorated with depth markings and Oris logo. The watch has a WR of 500 meters.

Dial and hands

Looking at the dial is looking into great depths. The dial itself, due to the inner depth scale, the water channel and applied indices, gives you that 3D effect. The dial has chrome plated applied indices with luminova, matching the very good looking handset. Slightly wider hour and minute hand, not plongeur style, but very well executed. Date window at the “6”position. The dial is market Depth Gauge in red writing above the date window. Further more the dial has Oris, automatic, pressure resistant and 50bar/500m printed on the dial. All in good proportions.


The movement is the a Oris Cal. 733 commonly known as Sellita SW200-1 and is based on the ETA 2824 movement. Nothing fancy like an inhouse movement or anti magnetic systems. Power reserve app. 40 hours.


The Oris Aquis depth Gauge comes with a yellow rubber strap that features a new innovation, the safety anchor. This prevents the strap from breaking loose, even after a severe impact. And you will get a second black rubber strap as well and a cool tool box to keep your watch in.

Final thoughts

I have owned several divers in the price range of 2.500-5.000 euro. But this Oris Aquis depth gauge is something special. For app. 3.000 euro you will buy a real and practical diving watch, a honest tool watch with a unique depth system. It is very well executed and if you are looking for diving watch, don’t forget this beauty!! You won’t be disappointed!
