Sinn 656

Used good condition Sinn 656. The watch was originally purchased in 2009 and comes on a brand new and unused Sinn leather strap with Sinn pin buckle, used Sinn rubber strap with extension, Sinn deployant clasp, strap change tool, box and instructions. The 656 is now discontinued and was originally conceived for the instrument panels of aeroplanes and helicopters, and optimised to provide rapid and clear readability, they are specifically designed to offer time measurement in its purest form. And they have now inspired us to create a watch with these same characteristics (and Magnetic Field Protection of up to 80,000 A/m) to complement our range of instrumental chronographs.

The dial design ensures especially clear readability:

  • Maximum contrast of the hands, indices and numerals against the glare-free black dial.
  • Extremely large numerals for intuitive orientation even in low light levels.
  • Striking hand profiles.
  • Special long-lasting, luminous paint on the minute and hour hands and indices to ensure accurate reading even in adverse conditions
