The reference SPB087J has the Seiko 6R15 (automatic) movement which has a power reserve of 50 hours. This movement ticks at 21,600 vibrations per hour. The watch has a screw-down crown and caseback, to ensure the 200 meters of water resistance. Normally, you will find Seiko’s own Hardlex mineral crystals on their watches in this price range, but for this special edition SPB087J1 Seiko PADI Sumo made an exception and used a sapphire crystal.
