Commentary
Sinn Series U50 HYDRO dive watch combines the brand’s signature HYDRO technology with a sleek and sporty design. The HYDRO technology fills the case with silicone oil, which eliminates the risk of condensation, improves readability, and protects the movement from external pressure. The U50 HYDRO has a 41 mm stainless steel case that is water-resistant to 5000 meters and features a unidirectional rotating bezel with a ceramic insert. The dial is black with white indices and hands, and has a date window at 3 o’clock. The U50 HYDRO line has 3 different models, the U50 HYDRO S with an all black case, the U50 HYDRO SDR with a steel case with black bezel, and the U50 HYDRO in an all stainless steel case without any black coating.
The watch is powered by a Ronda 715 Li movement with a long service life lithium battery. While not expressed by Sinn, Ronda claims that this battery expectancy is 10 years.
The Sinn Series U50 HYDRO dive watch appears to be an ultra reliable watch for the dive watch enthusiast that wants a refraction free watch with incredible readability underwater. The 10 years battery life is also very reassuring for those who dislike frequent battery changes.
Press release
When impressive functionality, perfect readability and technological innovation come together, the result is versatile and robust timepieces such as the watches in the U50 HYDRO series – all of which have a comfortable diameter size of 41 mm!
One of the outstanding features of the U50 HYDRO, U50 HYDRO SDR and U50 HYDRO S is concealed inside the diving watches, meaning that its incredible effect becomes most evident under water: HYDRO Technology. The benefits never fail to impress experienced users: reflection-free underwater readability from any angle, absolute freedom from fogging and – thanks to the special oil filling – water-resistant and pressure-resistant up to a diving depth of 5,000m. All three watches focus on a striking design with a display that concentrates on the essentials. They owe their outstanding suitability for everyday use to high-quality features with special materials, which ensure that the watches can withstand even the most adverse conditions.
Whether for professional use or to cope with the demands of diving, all three watches are perfect for such challenges – as has also been confirmed by independent classification company DNV. On our behalf, it tests and certifies pressure resistance to a diving depth of 5,000 m (= 500 bar) and temperature resistance and functionality in accordance with the European diving device standards
Due to the aforementioned oil filling, these three timepieces must be quartz watches, as the oscillation of the balance in a mechanical watch would be unable to overcome the high friction resistance of a liquid medium. Nevertheless, watch lovers needn’t forgo the reliability typical of SINN – the long-lasting lithium battery used ensures reliable function at temperatures ranging from – 20 °C to + 60 °C. The battery also has an exceptionally long service life. The movement’s integrated EOL (end of life) function prevents the watch from stopping suddenly.
Top suitability for everyday use
All three watches focus on a striking design with a display that concentrates on the essentials. They owe their outstanding suitability for everyday use to high-quality features with special materials, which ensure that the watches can withstand even the most adverse conditions. The case and crown are thus made of high-strength seawater-resistant German Submarine Steel. It is characterised by its extreme strength and exceptional non-magnetic properties. Another advantage that stands out for connoisseurs is its outstanding resistance to seawater. As a result, we have designed the rotating bezel to be captive in the case. Thanks to the use of TEGIMENT Technology to harden the surface, it can also easily withstand high external stresses. The result: exceptional scratch resistance. The positioning of the crown at 4 o’clock also deserves special attention. This prevents pressure on the back of the hand – even during physically demanding activities.

The long history of HYDRO
The use of HYDRO Technology in the U50 HYDRO series is just the culmination of more than 25 years of development and innovation. Indeed, we look back on an extremely successful history with this technology, not least because it is inextricably linked with such renowned names as the GSG 9. After all, in the case of the UX, professional users in particular appreciate the practical benefits of HYDRO Technology. The first model to unveil the technology was the 403 HYDRO in 1996. As well as setting the benchmark, this watch provided the inspiration for the next milestones, which were reached in 1997 with the launch of today’s legendary mission timers: the EZM 1 – equipped with a mechanical movement – for the special unit of the Central Customs Support Group ZUZ (Zentrale Unterstützungsgruppe Zoll) and the EZM 2 – with HYDRO Technology – for the maritime unit of the German Border Protection Group 9 (GSG 9). Further highlights included the UX (EZM 2B) series and, above all, the UX GSG 9 (EZM 2B) series for the maritime unit of a special German police task force (2004/2005). Our UX S model has been used by soldiers in Germany’s commando frogman force KSM (Kommando Spezialkräfte der Marine) since 2016.
