The Sinn 156 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 created cockpit navigation clocks. The watches in this collection have the complication of a chronograph for optimal timekeeping and a contemporary appearance of the dial. The 156 watches are functional and attractive, coming in a variety of colours and finished with a high-quality automatic movement. Sinn is known for building their watches with the best materials and precise engineering, and this collection is no exception. The Sinn 156 watches are as historic as they are contemporary. 

Core Features of the Sinn 156 Collection.

• The Sinn 156 Collection features instrument chronographs with a contemporary take on a historic pilot’s chronograph design.
• All of the watches in the collection have cases made of bead-blasted stainless steel. This feature contributes to the contemporary aesthetic of the collection. 
• Each watch features scratch-resistant sapphire glass to protect the dial with anti-reflective treatment on both sides. 
• The Sinn 156 watches are all waterproof and pressure-resistant to 10 bar. They are also low-pressure resistant. The screw-fastened case back is designed to ensure this water resistance. All of the watches meet the requirements for waterproofness, as set out in standard DIN 8310.
• Every Sinn 156 watch is powered by an automatic, self-winding movement of the calibre SZ01. This movement uses 28 bearing jewels and 28,800 semi-oscillations per hour to power the timepiece. It also has a seconds stop function and is anti-magnetic as per DIN 8309.
