Commonly called the “Sumo” model, this Seiko Scuba automatic diver’s watch features the 6R15 movement and 200m of water resistance. This watch earned its nickname due to its bold, oversized case styling, thick bezel fonts, and the distinctive 12 o'clock marker that resembles a sumo wrestler's mawashi (loincloth)
