Sinn are a brand with a solid reputation for producing incredibly high-quality timepieces that are powered by precisely engineered movements. The brand was founded in Frankfurt, Germany by Helmut Sinn in 1961. Since then, the brand has sent its watches to the deepest part of the oceans and all the way into outer space in an effort to prove the robustness and reliability of the timepieces, even in the most adverse conditions. Sinn is known amongst watch enthusiasts as being one of the most innovative and technologically advanced brands in the market, making their watches very desirable and collectable.

The Sinn 356 watches are based on the classic Sinn 356 instrument chronograph. Each of the timepieces is incredibly functional with its three sub-dials and each watch is built using the highest quality materials. The watches all feature some of the famous Sinn Technologies to add to the smooth running and longevity of the timepieces. These robust models will be able to accompany the wearer through daily living and great adventures.
