The new SPB153J Seiko Prospex Divers based on the classic 6105 wristwatch, with its stunning Green Dial and One way rotating Bezel. The Sapphire crystal glass is slightly faceted as it meets the bezel. Powered by the automatic caliber 6R35, which has a power reserve of 70 hours. The Stainless Steel (super hard coated) case measures 42.7mm in diameter, but a relatively slim 13.2mm in thickness. Once again, the slightly curved case and low profile makes it extremely comfortable on the wrist. Lumibrite on hands, indexs and bezel,
