The Sinn 903 series has a facinating historie. When Mr Breitling was losing his health and liquidated the business at the end of the seventies, he sold several trademarks like ‘Chronomat’ , ‘Navitimer’ and designs. So Sinn became owner of the Navitimer design and developed the Sinn 903. This model now is just as iconic as the Breitling Navitimer. Especially when you have the Sinn with the Lemania caliber.

This 903st HD is the one with the famous Lemania caliber and is in very good vintage condition. Comes on an original Sinn canvas strap and Sinn box. This watch has been serviced in september 2022 by a generic watchmaker. 3 months warranty!
