TIEFENMESSER WHITE DIAL STEEL FIRST GEN CALIBER
Immersion is imminent.
A submarine quietly folds into the unfathomable depths of the ocean, disappearing without a trace from the surface and taking with it a world whose space is enclosed in heat and wetness…
The TIEFENMESSER collection takes its inspiration from the materials that feature so prominently in submarine equipment: the steel of the instruments measuring pressure and depth.
Stainless steel case with satin and polished finish, mounted on a stainless-steel bracelet.
Powered by RESERVOIR’s first generation calibre: a self-winding mechanical movement combining an exclusive, patented 124-piece module on an ETA-2824, to bring to life the retrograde minute, jumping hour and a 37-hour power reserve.
Delivered in a prestigious wooden box with an additional NATO strap.

Bring boldness back to life
RESERVOIR’s manifesto centres on bringing boldness back to the experience of time. Rather than something passive, time is treated as a moment of intensity, where focus sharpens and every second matters. The brand’s philosophy encourages living fully in the present, driven by energy, risk, and determination.
This mindset is reflected in the design of its watches. Inspired by precision instruments from automotive, aeronautical, and marine worlds, RESERVOIR timepieces adopt the visual language of gauges and counters. Their signature display replaces traditional hands with a retrograde minute, jumping hour, and power reserve, creating a functional, high-impact design that makes time feel dynamic and purposeful.
