The Shell Mates have surfaced. Now it’s your turn to decide who stays with you.
The Fleuss Automatic SpongeBob SquarePants Shell Mates Limited Edition brings together the technical foundation of a dive watch with a layer of character that moves with you. At its core is a reliable automatic movement housed within a 43mm stainless steel case, built to perform with confidence in changing environments both above and below the surface.
Built for the Deep. Defined by Character.
A custom second hand transforms the passage of time into something more expressive, creating a constant sense of presence with every movement. In low light, Swiss Super-LumiNova illuminates the dial, revealing a more playful and unexpected side of the watch. Turn it over, and the exhibition caseback offers a view into the mechanics within—a reminder that beneath every surface, precision is always at work.
Limited. Numbered. Available Now.
Each variant is produced in strictly limited quantities, with every piece individually numbered as part of the collection. Whether drawn to quiet detail, bold character, or something more free-spirited, there is a companion that resonates with the way you move through the world.
