The Seiko 5 Sports SRPK91 is an automatic watch inspired by the Seiko 5 Sports SNXS series. It has a more compact case and bracelet than the original, and its lower center of gravity helps it sit comfortably on the wrist.
The case is stainless steel with hairline and mirror finishes and a curved Hardlex crystal. A screwdown see-through caseback shows the movement at work. The ivory dial has a sunray finish, a metallic minute track, diamond cut indices and a day/date calendar. LumiBrite on the hands and markers improves visibility in low light.
The Caliber 4R36 automatic movement runs on wearer motion and can also be wound by hand. The stainless steel bracelet closes with a tri-fold push button release clasp. The watch is water resistant to 10 bar (100 meters).
