The Sea Star Automatic Dive Watch comes in a sturdy stainless steel 316L case and bracelet. It's powered by Swiss made Sellita Caliber SW 200-1, which is an automatic movement with 26 jewels, 28,800 bph, and a power reserve of 38 hours. The crystal is scratch resistant sapphire, with a screw-down crown for added water resistance of 300 meters. It also has luminous hands and markers for easy viewing in low-light conditions. The dial is gorgeous with a combination of polished ceramic bezel and matte black finish for an understated but luxurious look.
