The Sinn U50 HYDRO S 1051.020 is an incredible Made in Germany diving watch. If you are familiar with Sinn watches the U1's little brother, the U50, normally needs no introduction. Little may be a bit of a stretch as the watch is still 41mm in diameter, but Sinn has expanded the U50 line with an amazing innovation. As you may notice from the name, this is no regular U50! The watch is filled with oil (the Sinn HYDRO technology) which allows for an incredible water resistance, alongside absolutely impeccable legibility from all angles.

Let's start with the easy part: the watch is stylish and extremely legible. Every element has a great mix of the iconic design with practicality and functionality added in. When you wear an U50 it will stand out in a discreet manner showing the right mix of popping red elements and simple colours, without falling for the tendency of watch manufacturers to overdo things. 

But the real gem is in the technical elements of the watch as those are absolutely top notch. This is a well balanced, comfortable watch due to the crown at 4, extremely well designed bracelet and case design. But it's also a very serious watch with 5000m water resistance (DNV certified), the bezel, case and bracelet have a Black Hard coating based on tegiment technology, with a Ronda 715 Li Swiss Made quartz movement under the hood. 

The U50 is versatile, it's practical, it's iconic, it's quite simply one of the best diving watches out there.

  2 year warranty

  We offer a 2 year warranty on all watches. This covers all mechanical malfunction arising from parts failure and/or assembly errors. Excluded are parts that by their nature may not last 2 years, like batteries and leather straps, damage/problems caused by improper use and wear and tear. We stand behind the brands that we sell and the quality that they offer.
  Some of our brands also offer an international warranty, which will also apply.

  Service and parts

  In the unfortunate event of a problem with your watch, you simply need to send it to us (or take it to another dealer if the brand offers an international warranty). We have access to the official service centers, where only original parts are used and the watchmakers are qualified and experienced with your type of watch. Not every watch movement is the same, so it's best if it's handled by people who know what they are doing.
  After your 2 years warranty has expired we are able to offer service in most cases.
