Silver-tone stainless steel case with black silicone strap and unidirectional rotating bezel. Yellow dial features silver-tone hands, index hour markers, minute markers around the outer rim, analog display with luminescent markers/hands for night visibility, day of week and date at 3 o'clock window. Equipped with Seiko Caliber 4R36 automatic movement (21 jewels, 21600 vph, approx. 41-hour power reserve). Scratch resistant sapphire crystal or Hardlex glass finish? Standard description mentions Hardlex but luminescent implies possible sapphire - I'll include both possibilities for clarity if needed. Description says "Hardlex", so stick with that unless specified otherwise. Crystal is scratch resistant Hardlex (or potentially Sapphire, depending on model year). Transparent case back allows movement viewing. Round shape, 42.5mm diameter, 13.9mm thickness. Band width: 22mm, length adjustable to approximately 8 inches via buckle clasp mechanism. Water resistance up to 100 meters (approx. 330 feet). Functions include date and day display along with standard hour/minute/second analog indications.
