Sinn 717 Cockpit Wristwatch Black Leather Strap

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 717 watch is a classic cockpit wristwatch. The design of the watch is inspired by that of the Nabo 17 ZM cockpit clock. This clock was used in combat aircraft and military helicopters. The dial of the watch has been especially designed to be easy to read in the dark to emulate the appearance of the original clock. This watch is a fine example of how much importance Sinn places of horological heritage and how the brand aims to translate it into the modern day.
