Our take on the Seiko 5 Sports Automatic SRPK91

The Seiko 5 Sports SRPK91 is an automatic watch that revives the compact case style of the classic SNXS series. It runs on Seiko's 4R36 movement with 24 jewels, hacking, manual winding, and about 41 hours of power reserve. The stainless steel case and bracelet, sunray dial, and LumiBrite hands give it a versatile look that suits daily wear. Compared with larger Seiko 5 models, it wears smaller and more comfortably, though the bracelet and lack of sapphire crystal are common cost-saving trade-offs.

About the Seiko 5 Sports Automatic SRPK91

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).
