The clean lines of the case of the 456 series with the striking narrow ring around the dial are highlighted by the sophisticated use of gold: solid 18-carat gold forms a charming contrast to the stainless steel elements on the band lugs and the crown. Pure, clean materials are combined to produce a look of timeless elegance. The designs of the dials also meet this standard. Regardless of which version of the 456 St 18 kt you prefer, the sapphire crystal glass with anti-reflective coating on both sides always gives you a clear overview of the state of things in each 456. You'll also enjoy a fine detail on the other side of the watch: the sapphire crystal glass back offers fascinating glimpses of the functional sophistication of the automatic movement. Whether you prefer the elegantly sporty leather strap as the perfect complement to the bicolored version of the Sinn 456 or the gracefully designed bracelet of solid stainless steel with gold intermediate links is completely up to you.
