Product Identity

The Seiko SRPK18 is a gold-finished automatic watch built for daily wear and water-based activities. Its 42.5 mm case and 100 metre water resistance suit both office and outdoor settings.

Mechanical Operation Limits

The Caliber 4R36 movement runs at 21,600 vibrations per hour with 24 jewels and a 41-hour power reserve. Accuracy depends on regular wrist motion; the watch stops if left unworn for longer than the reserve.

Compatibility Check

Verify the 22 mm lug width matches any replacement strap you plan to use. Confirm the 13.4 mm case thickness fits under your shirt cuffs. The screw-down crown must be fully tightened before water exposure to maintain the 10 bar rating.

Questions about this item

Which Seiko 5 Sports Special Creation version should I choose?

This reference SRPK18 comes in a single 42.5 mm stainless-steel case with gold finish, black dial, Hardlex crystal and 22 mm lug width; no other case sizes or colourways are offered for this model.

What does the 21,600 vibrations-per-hour figure mean on the wrist?

The Caliber 4R36 beats at 21,600 vph (6 beats per second), giving a smooth sweeping seconds hand and a typical daily rate within Seiko's standard tolerance for this movement.

What does the 10 bar / 100 m water-resistance rating allow in practice?

The screw-down case back and crown provide 10 bar resistance, suitable for swimming and snorkelling but not for scuba diving or high-velocity water sports.
