Seiko 5 Sports SRPL77K1 [PRE-ORDER]

The Seiko 5 Sports SRPL77K1 is a compact, no-nonsense timepiece that packs a punch in both style and performance. It runs on Seiko’s trusted 4R36 automatic movement, which you can also wind manually, and gives you around 41 hours of power reserve—perfect for daily wear.

With 24 jewels inside, it keeps time smoothly and reliably. The stainless steel case is nicely sized at 38mm across and 12.1mm thick, making it comfortable without feeling bulky. It features a durable Hardlex crystal and a see-through screw-down case back that lets you admire the inner workings.

The dial includes a day-date display and glows in the dark thanks to LumiBrite on the hands and markers. It’s water-resistant up to 10 bar, offers magnetic protection, and secures with a sturdy three-fold clasp. Add the unidirectional rotating bezel and you’ve got a watch that’s sporty, dependable, and effortlessly cool—ready for whatever your day throws at you.
