The Story
Built for the everyday adventurer, the Seiko 5 Sports SRPG27K is a men's automatic watch from the Field Series that runs entirely on movement — no battery required. The self-winding Calibre 4R36 powers itself through the natural motion of your wrist, and can also be wound by hand when needed, giving you complete control.
Once fully wound, the watch runs for approximately 41 hours, so it keeps ticking through a weekend without wearing it. A handy day and date display sits on the dial for quick reference, and the stop-seconds function lets you set the time with precision. The LumiBrite coating on the hands and hour markers glows in the dark, making the watch easy to read whether you're up before sunrise or out after sundown.
Designed to keep up with an active lifestyle, the SRPG27K is water resistant to 100 metres and resists interference from everyday magnetic fields — think bag clasps, speakers, and laptop cases. The curved Hardlex crystal protects the dial from bumps and scratches, while the see-through case back gives you a glimpse of the movement working inside.
The 39.4mm stainless steel case sits comfortably on the wrist without feeling oversized, and the three-fold clasp with push-button release keeps things secure throughout the day. A versatile watch that works just as well on the weekend as it does in the office.
