Seiko Seiko 5 Sports · Automatic Watch
SRPJ81
Model / SKU: SRPJ81
The Seiko SRPJ81 channels classic field and aviator watches into a compact 36mm stainless steel case and bracelet. Its black dial features a 60-minute outer track and an inner 13-24 hour military scale, with luminous hands and markers and a red-tipped second hand keeping everything sharp. A day/date calendar handles the practical side of daily wear.
Driving it is the automatic Caliber 4R36, running at 21,600 vibrations per hour with manual winding, 24 jewels, and about 41 hours of power reserve, visible through the see-through caseback. A tri-fold push-button clasp and 100-meter water resistance finish the build. Stop by our Willis, TX store to slip it on and see how it feels.
