By TLex Sorry folks it's not based on the new SBDX011 auto (that would have been cool), but the SBBN013 which is powered by Seiko's in-house quartz caliber 7C46 with seven jewels. The only difference is its new white ceramic shroud, hence the name 'White Dolphin' err, shouldn't that be Beluga?! It's case measures 49mm x 15.3mm and is water-resistant to 1'000m. The 300 pieces of the SBBN019 were released for sale as of August. Awe, what a cute lil cetacean!
