A beauty, all in white: The light silver-plated dial of this Orion features silver indexes and hands, creating a celestial aesthetic. The inner workings are also extraordinary: the highly praised manual NOMOS caliber Alpha. The leather strap made of the finest Horween Genuine Shell Cordovan is as black as ebony—and just as long-lasting.
