Part of the Seiko 5 Sports Field series, this model is built to suit a wide range of situations, from outdoor leisure activities to daily urban wear. The watch is powered by the reliable Caliber 4R36 automatic movement, which offers both automatic and manual winding capabilities, ensuring accurate timekeeping without the need for a battery.

 

The SRPJ81 features a striking black dial with a 60-minute track on the outer edge, a design element inspired by vintage field and aviator styles.

The black dial is protected by a Hardlex crystal, a material known for its scratch resistance. The watch's 24-jewel movement operates at 21,600 vibrations per hour, delivering smooth, reliable timekeeping. The exhibition case back allows a view of the automatic mechanism in motion, adding a layer of mechanical interest for enthusiasts.
