The Sinn 104 St Sa I W Leather 104.012 embraces the soul of Sinn very well, by combining a less is more design, with practicality and a very high quality level.

The watch has all the basics right, such as 200m water resistance, sapphire glass with an AR coating, a comfortable leather strap and a solid SW 220-1 mechanical movement. But it goes beyond that with a bi-directional Captive pilot's bezel, DIN 8309 anti-magnetism, display case back and a very comfortable case design. It shows how much thought and effort went into this watch, that may appear to be solely utilitarian at a first glance. On your wrist it will be a very refined presence, while the quality will ensure a reliability and practicality.

  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.
