At this year’s WatchTime Düsseldorf, Germany’s largest watch event, Sinn Spezialuhren once again reaffirms its mastery of functional engineering and purpose-driven design. The Frankfurt-based manufacturer introduces two new models — the U50 B and the U1 S L — each redefining what it means to combine technical precision with striking visual presence.

These latest creations showcase Sinn’s ongoing commitment to innovation in diving instruments, balancing uncompromising durability with distinct design language and unmatched readability.
U50 B: Matt Blue Meets Depth
The new U50 B continues Sinn’s tradition of building watches that perform flawlessly in the harshest underwater conditions — and look exceptional doing so. Its matte blue dial commands attention, projecting calm authority and clarity.

White luminous indices and hands create a sharp contrast, ensuring superb legibility even in low-light conditions, while the dial’s tonal harmony conveys an understated confidence both above and below the surface.

True to Sinn’s heritage of technical innovation, the U50 B is crafted from high-strength, seawater-resistant German submarine steel, a material prized for its exceptional robustness and non-magnetic properties. The captive diver’s bezel — a hallmark of Sinn’s engineering — is treated with the brand’s proprietary TEGIMENT Technology, providing outstanding scratch resistance.

For those seeking the ultimate in resilience, Sinn also offers the U50 B with the TEGIMENT-enhanced case, further reinforcing its reputation as one of the most durable mechanical diving instruments on the market.
Tested and certified by an independent institute, the U50 B meets the stringent criteria for professional diving equipment. Whether accompanying deep-sea expeditions or daily wear, it exemplifies Sinn’s perfect union of technical precision, pragmatic design, and rugged beauty.
Retail Price (incl. tax):
● U50 B: from SGD 4,400
● U50 B with TEGIMENT Technology: from SGD 4,940
U1 S L: Clarity. Simplicity. Luminosity.
If the U50 B is defined by depth, the U1 S L is defined by light. Limited to just 300 pieces worldwide, this extraordinary model represents a breakthrough in luminous technology — achieving an unprecedented level of brightness and readability in total darkness.

The innovation lies in the entire dial and bezel marker, which glow with exceptional intensity thanks to a pioneering manufacturing process. By integrating luminous paint into a mould using a special casting technique, Sinn has created a hybrid ceramic component bonded to a metallic base dial.

The result is a dial that delivers uniform, long-lasting luminosity across a large surface area — a feature that not only enhances readability but transforms the watch into a beacon of modern craftsmanship.

Beyond its technical brilliance, the U1 S L retains the minimalist, purpose-driven aesthetic that defines Sinn’s design philosophy. The case and crown, made from high-strength, non-magnetic submarine steel, guarantee superior seawater resistance. The addition of a Black Hard Coating, applied via TEGIMENT Technology, provides a sleek, tactical finish while improving scratch resistance.
Certified by an independent institute, the U1 S L is water-resistant to 1,000 meters (100 bar) and complies with European diving equipment standards for both temperature resistance and functional reliability. It is, quite literally, a watch made for the darkest depths.
