Sinn 903 St: The Navitimer from Frankfurt

There is a plausible reason why the Sinn 903 St looks so similar to the Breitling Navitimer. In addition to the classic 903 St, the Frankfurt company Sinn Spezialuhren GmbH also produces heritage models of the Sinn 903 and variants with different dials. All versions of the 903 series are water-resistant to depths of 100 metres.

At CHRONEXT you can obtain the Sinn 903 St as well as many other models from the German manufacturer at fair prices. Every watch is checked for authenticity by our in-house master workshop and is provided with our 24-month CHRONEXT warranty.

SA roots

The founder of Sinn Spezialuhren GmbH, Helmut Sinn, was not only a pilot in his heart and soul but also a skilful businessman. When Breitling stopped production in 1979 due to financial difficulties, the then 63-year-old secured the individual parts of the Navitimer and then produced the model under the name Sinn 903. Breitling lettering can be found on various components, especially in Sinn 903 St vintage models; in the early days of the Sinn model, some dials even bore the inscription "Sinn Navitimer".

Sinn 903 St

Over 40 years of model diversity

Meanwhile, Sinn has been producing the 903 for more than 40 years. While the Sinn 903 St with the black dial is considered the classic model of the collection, Sinn chronographs are now available in numerous versions. Among the most popular versions of the collection are the Sinn 903 St in silver, which has a silver dial galvanized with a silver-nickel layer, and the Sinn 903 St B E with vintage luminous material and dark blue dial, which was launched in 2015.
