TWR Watch Repairs, based in Rayleigh, Essex are proud to have been appointed the official UK Sinn Service Centre. 


TWR Watch Repairs is a modern watch repair and servicing centre with a purpose-built workshop equipped with state of the art technology. 


The name Sinn Spezialuhren stands for highly functional mechanical watches.


Sinn's pilot watches, diving watches, chronographs and Mission Timer (Einsatzzeitmesser / EZM) are designed to impress not only pilots, divers, and the German federal police special force GSG 9 (Grenzschutzgruppe 9). SINN watches continuously prove their toughness, durability, high quality and precision in both everyday and extreme situations.


These characteristics are due in no small part to the incorporation of special technologies including DIAPAL, Ar-Dehumidifying Technology, HYDRO and TEGIMENT. When Sinn Spezialuhren develops a new watch, its form is always dictated by the required function.

"Just a quick email to say I have received my Sinn 104 watch with the new glass fitted.

The girl I talked to on the phone gave me accurate information. My Sinn 104 was returned quickly, I received progress reports keeping me up to speed telling me what needed to be done to the watch, when it would be posted and when I would receive it. An excellent and efficient speedy service."
