The Sinn 900 Collection is a family of pilot’s chronographs. The pilot’s watch is a signature style in Sinn history as the brand’s origins are rooted in creating cockpit navigation clocks. The watches in this collection have the complication of a chronograph for optimal timekeeping and a classic appearance of the dial. The 900 watches are functional and attractive, coming in a variety of colours and finishes with a high-quality automatic movement. Sinn are known for building their watches with the best materials and precise engineering, and this collection is no exception. The Sinn 900 watches bring together a range of Sinn Technologies to create high-performance timepieces. 

Core Features of the 900 Collection:

• The 900 Collection combines a number of Sinn Technologies to create a high level of reliability for time measurement and functionality. 
• All of the 900 watches feature Ar-Dehumidifying Technology. This enhances the functional reliability of the watch and minimises fogging.
