Prospex SRQ055J1 [PRE-ORDER]

The Seiko Prospex SRQ055J1 is a timepiece that doesn’t just measure time—it commands it. With its 8R48 automatic movement, this chronograph delivers precision and power, offering up to 45 hours of reserve and tracking time down to the second, minute, and hour.

It’s built with 34 jewels and includes a date display, making it as functional as it is refined. The stainless steel case, finished with a super hard coating, has a bold 42mm diameter and a substantial 14.6mm thickness, giving it a confident presence on the wrist. A dual-curved sapphire crystal with anti-reflective coating keeps the dial crisp and clear, while LumiBrite on the hands and indexes ensures visibility even in the dark.

With a tachymeter scale, screw-down case back, and water resistance up to 10 bar, it’s ready for action. Weighing in at 191 grams and secured with a three-fold clasp, the SRQ055J1 is a serious watch for those who appreciate mechanical artistry with a sporty edge.
