Ressence Type 5 AIT

Meet Type 5 AIT (Art In Time), Ressence's latest creation. This limited edition collaboration with its partners Art In Time in Monaco perfectly illustrates a contemporary approach of originality and innovation.

The Type 5 AIT is an extension of the TYPE 5 dive watch. Defined by its bold, organic case, oil filled dial, clear legibility and ruggedized bezel.

The Type 5 AIT will undoubtably be recognised for its vibrant yellow notes on the dial, markers, and bezel. There will be 11 watches, each unique and available exclusively at Art In Time. The 12th watch with a distinctive yellow Ressence logo will be sold at a charity event in September with all proceeds going to the Fondation Prince Albert II de Monaco.

The Foundation

In June 2006 HSH Prince Albert II of Monaco decided to set up a Foundation dedicated to protecting the environment and promoting sustainable development at local and global level. Since then, active all over the world, the Prince Albert II of Monaco Foundation has sought to bring together scientists, political leaders and economic and civil society stakeholders behind a vital objective for our future – protecting the ocean and the land. The Foundation’s long-term action has led to some encouraging victories being won, whether in safeguarding endangered species or improving living conditions in rural communities by implementing new sustainable and ethical solutions.

The Pelagos Sanctuary is a marine territory of 87,500 km2 in the waters of the Principality of Monaco, France and Italy, the three states being signatories of the Pelagos Agreement. The Sanctuary is home to a remarkable biodiversity, with many species of marine mammals such as dolphins, cachalots, and fin whales.

The Prince Albert II of Monaco Foundation, the WWF, the IUCN and MedPAN have joined forces to create the Pelagos Initiative to support the protection of this unique area. This commitment of civil society aims to fund activities for the protection, conservation and promotion of the Sanctuary, in accordance with the management plan of the Pelagos Agreement.

We here at Ressence couldn’t be prouder of that fact that all proceeds from the sale of this very special limited-edition watch will go to the foundation. At our core we aim to work with nature, not against it.


The case is crafted entirely in grade five titanium, which contributes to its light weight in the hand and on the wrist (with the strap included, the watch weighs just 85 grams). The tapered case has a sandwich-style construction with a two-tone finish, showcasing both polished and satin finishing textures.

Dial side, the hours’ disc (adorned with a logo) has a yellow index at the hour that the watch corresponds to. This will be unique to the owner. Below the oil-filled upper chamber is an air-filled lower chamber that houses the bespoke mechanical auto-winding movement. Using a magnet transmission to drive the discs on the ROCS dial. Seven bellows compensate for the expansion and contraction of the oil in the upper chamber as temperatures change. The use of oil has one ultimate advantage. It cancels out what is known as Total Internal Reflection. Typically, under water, a traditional diver’s watch needs to be viewed straight on in order to be read properly - otherwise refraction turns the glass into a mirror. But not with the oil-filled TYPE 5. The use of oil ensures complete legibility whatever the angle of view. A first for a mechanical watch.

The rear-mounted crown deploys the Ressence Compression Lock System (RCLS), a mechanism which closes the gasket sealing of the lower air chamber when the crown is pushed back into its resting position.

Art in Time

Art In Time is based in Monaco and boasts a unique concept in watchmaking bringing together smaller production brands on the basis of their common values: independence, creativity and exclusivity. Throughout both his personal and professional career, Karl-Friedrich Scheufele has developed a large number of initiatives closely related to the theme of time and the preservation of watchmaking heritage. This is the second charitable initiative that Mr. Scheufele and Art in Time will partner with Ressence on. Proceeds will go to the Fondation Prince Albert II de Monaco.
