The U50 was introduced in 2020 as a smaller alternative to the U1, with a reduced case diameter and thickness.
The steel case provides a substantial feel, reinforcing its identity as a professional dive watch.
A new feature on the steel bracelet is a toolless micro-adjustment system for easy clasp resizing.
The U50 features signature U-series blocky markers and hands, with single-tone lume and red accents.
The movement, Sellita SW300-1, allows for a thinner case profile while maintaining a 500m depth rating.
Available versions include standard steel, steel with a black bezel (SDR), and all-black (S).
The U50 is also offered with Tegiment surface hardening for enhanced scratch resistance and in oil-filled Hydro models for improved underwater readability.
The standard stainless steel U50 is presented as the core model of the series, embodying Sinn's practical and functional design philosophy.
