Striking form, sparse dial design, superior readability – characteristic SINN features which highlight the similarities between the 556 series and our pilot and navigation cockpit clocks.
The accentuation of the hours, minutes and seconds plus the satinized stainless steel case are what give the watches their sporty yet elegant appearance. The crystal of the 556 watches is made from sapphire crystal, as is the transparent back which provides an intriguing insight into the filigree mechanical movement inside.
