Nomos Glashutte Watch Club Sapphire Crystal 703.1. This youthful wild spirit with a thick steel bezel and robust lugs is the perfect watch for life. Black-and-red hands set the tone, while the striking numerals and indexes characterize the white silver-plated dial. The sapphire crystal glass back protects the hand-wound Alpha caliber from NOMOS within—as only a diamond would be harder.
