I purchased this at an authorized retailer as a gift, but I didn't end up giving it, so I'm putting it up for sale. This is the now-discontinued but still popular Prospex Sumo. I bought it as a gift, so the band is unadjusted and it's brand new and unused. ■ Brand: SEIKO Seiko ■ Model Number: SBDC031 ■ Material: Case/Stainless steel, Belt/Stainless steel ■ Size: Face (HxWxD): Approximately 42x45x13mm (excluding the crown), Wrist circumference maximum: Approximately 190mm ■ Movement: Automatic winding ■ Water resistance: 200m water resistance ■ Dial color: Black ■ Specifications: Date display, unidirectional rotating bezel Thank you.
