Ressence Type 5 AIT is a Dive Watch That Gives Back to the Ocean

When you mention Monaco, a lot of different things may come to mind. One of the more stunning should no doubt be the Pelagos Marine Sanctuary. Consisting of 87,500 square kilometres of marine habitat, the Pelagos Sanctuary represents an agreement between Italy, France, and Monaco to protect marine mammals of the Mediterranean, such as the striped dolphin, the long-finned pilot whale, the fin whale, and the bottlenose dolphin. It’s an inspiring effort—so inspiring, in fact, that it is the source behind the latest update to Ressence’s Type 5 AIT watch. Working with Art In Time Boutique in Monaco and the Foundation Prince Albert II de Monaco, Ressence created the new version and then dedicated it to the protection of the Pelagos Marine Sanctuary.

Built on a case machined from grade 5 titanium, the watch sports a pebble shape with domed sapphire crystals on both sides. Inside the case are two containers. The first container holds the mechanical movement, while in the other you’ll find the dial system. The second container is filled with 3.57 ml of oil, which helps to improve underwater legibility.

To compensate for the expansion and contraction of the oil due to temperature changes, Ressence had to develop a unique bellow system. The movement for this watch is a modified ETA 2824-2 that has been fitted with the ROCS—Ressence Orbital Convex System. Altogether, the movement has 41 jewels. It runs on a frequency of 28.8 vibrations per hour and has 36 hours of power reserve.

The Type 5 also has the unique feature of not having a traditional crown, so to wind the mechanical movement and to set the watch, you have to use the caseback. And when you’re underwater and you want to time your dives, you can use the uni-directional rotating bezel on the front. The dial offers a distortion-free visual (again, thanks to the oil).

The Ressence Type 5 AIT watch comes on a bright yellow premium rubber strap with a polished ardillon buckle. Only 12 pieces will be made of this special edition, all of which are exclusively available only through Art in Time in Monaco. The watch is priced at EUR 35,500.
