The elegantly sporty watch

Sinn’s much-loved 556 collection delivers quality, reliability and an understated aesthetic that holds its appeal over time. It is the perfect introduction to the technological world of SINN watches.

Striking form, sparse dial design, superior readability – characteristic SINN design features which highlight the similarities between the 556 series and their pilot and navigation cockpit clocks.

The accentuation of the hours, minutes, seconds and the date plus the satinized stainless steel case are what give the watches their sporty yet elegant appearance. The case front of the 556 is made from sapphire crystal, as is the transparent back which provides an intriguing insight into the mechanical movement inside.

The model 556 A RS has a special feature: a red second hand which contrasts against the black dial and white hands, numbers and indices to deliver optimal legibility, even in dimly lit environments.
