Sunray black dial reflects light with subtle depth, surrounded by polished indices and luminous hands that bring easy legibility. A date window sits at 3 o’clock, magnified under a cyclops lens built into the sapphire crystal. Stainless steel case and bracelet meet in a smooth, integrated design that wears comfortably and looks clean with just about anything. Under the hood, the Miyota caliber automatic movement offers a 45-hour power reserve and reveals its gold-toned rotor through an exhibition case back. Water resistance covers day-to-day splashes, and the bracelet secures with a tri-fold clasp that feels secure without adding bulk.
