icture this: you’re at an experimental art show. The room is dimly lit, filled with chatter and the clinking of glasses. As you check the time on your wrist, your luminous Type 5 L catches the eye of your neighbour. First, a brief eye contact. Then, a smile. And, in no time, here you are answering all their questions, exchanging ideas, and contact details to keep the conversation going.

In that moment, the Type 5 L proves our point — beyond functionality, a statement piece sparks connection, even in the most unexpected places.

Wait no more. The bright new Type 5 L is finally out in all its shine. And shine it does. At the movies or a wild rave, driving through a tunnel or exploring a bat cave, rest assured you won’t go incognito.

As clues are hard to ignore, you must have guessed what L stands for. Neither lemon nor lavender, but L as in ‘Luminescent’. Thanks to its full Super-LumiNova inlay, the entire dial casts a strong glow when the lights are low.

“This new beamer and latest addition to our line of mechanical watches is as much a tool watch as a conversation starter, thanks to its superior legibility and unique design,” says Benoît Mintiens, Founder of Ressence. “It’s not just about functionality; the robust Type 5 L brings a sense of quiet assurance and singularity to its wearer, making it a true companion for any endeavour.”

And by the way, you can also dive with it.

The Type 5 Luminescent will complement the Type 5 Night Blue and Black Black. It will be available worldwide via Ressence’s official retailer network.

The luminous enhancement of the Type 5 L is paired to the Ressence oil-filled upper chamber, a hallmark of every Type 5. The oil cancels out light refraction and makes the watch readable from any angle, providing a clear and crisp display that is essential for divers. The extra luminescent dial only further boosts this legibility.

The Type 5 L meets the rigorous ISO 6425 standard required for underwater exploration, adhering to the highest levels of safety and reliability. The watch is water-resistant up to 100 meters (10 ATM). It also passed tests of magnetic and shock resilience, among others. The robust Grade 5 titanium construction guarantees durability while maintaining a lightweight profile.

The Type 5 L features the unidirectional rotating bezel with an easy-to-grip tactile design, allowing for precise and reliable adjustments. This is a critical feature for divers who rely on their watch to track immersion time accurately. Additionally, every Type 5 caseback deploys the Ressence Compression Lock System (RCLS), a mechanism which enables wearers to lock the compression gasket for waterproofing.
