More Attitude


The Sinn 556 I RS has all of the great features of the bestselling Sinn 556 I, but our clients say the red seconds hand offers “a bit more attitude.”

The red seconds hand gives the watch a sporty look and feel, while still providing stark contrast against the matte black dial.


The Sinn 556 Series offers a great mix of performance, durability and classic Sinn design.  For these reasons, they are among Sinn’s bestselling watches of all time.
This version of the Sinn 556 RS is marked “I” for Indices only. 



Important features of this watch include:


  • Case made of satinized stainless steel
  • Sapphire crystal glass on both sides
  • Water resistant to 200 meters
  • Date display at 3
  • SuperLuminova on the hands and hours (glows green)
  • Inky black dial
  • Double antireflective coating
  • Low pressure resistant

This watch is fitted with a Sinn stainless steel H-Link bracelet.
