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 Prospex "Sumo," which remains popular even though it's been discontinued. By the way, the blue dial is not available in the new models. I bought it as a gift, so the band is new and unworn, and hasn't been adjusted. ■ Brand: SEIKO Seiko ■ Model Number: SBDC033 ■ Material: Case/Stainless steel, Belt/Stainless steel ■ Size: Face (HxWxD): Approx. 42x45x13mm (excluding the crown), Wrist circumference maximum: Approx. 190mm ■ Movement: Automatic ■ Water Resistance: 200m water resistance ■ Dial Color: Blue ■ Specifications: Date display, unidirectional rotating bezel Thank you.
