Core Features of the Sinn 104 Collection: 

• The SINN 104 Collection features five distinctive designs of the classic pilot’s watch. 
• All of the watches in the collection have cases and lugs made of polished stainless-steel. 
• A captive pilot’s bezel (a SINN technology) is attached securely inside the case. The bezel can be rotated on both sides and has a luminous triangle as a key mark at the 12 o’clock position. 
• Each watch features scratch-resistant sapphire glass to protect the dial with anti-reflective treatment on both sides. Sapphire glass is also used to create the transparent back of the watches and this is anti-reflection treated on the interior. The transparent back allows the wearer to observe and enjoy the mechanical movement inside. 
• The SINN 104 watches are all waterproof and pressure-resistant to 20 bar. They are also low pressure resistant. The screw-fastened case back and crown are designed to ensure this water-resistance. All of the watches meet the technical requirements for waterproofness, as set out in standard DIN 8310. 
• The watches are clearly structured for optimal readability. The functions include hours, minutes and seconds, date display, day of the week display and the pilot’s bezel. The date aperture is at the 3 o’clock position. 
• Every SINN 104 watch is powered by an automatic, self-winding movement of the calibre SW 220-1. This movement uses 26 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.
