Topper Jewelers is an Authorized Nomos Glashütte Dealer.

Extra large, an extra large date display—and extra blue: we call it siren blue, inspired by summer skies over the Côte d’Azur on hot August days. And for everything else, come what may: automatic watch Ahoi date siren blue holds tight to 20 atm, tells the time even in the dark, and looks great with a bathing suit, sneakers, or a suit.
