SEIKO 5 SBSA141 (SRPH29K1) – Military Spirit, Mechanical Strength

Tactical design meets everyday durability.

The SEIKO 5 SBSA141 / SRPH29K1 draws inspiration from military field watches, combining functional aesthetics with Seiko’s legendary 4R36 automatic movement.

 Featuring both self- and manual-winding, and a 41-hour power reserve, this watch is always ready — no battery required.

The stainless steel case houses a green dial with Lumibright hands and indexes, all protected by a curved Hardlex crystal.

Its see-through caseback lets you admire the movement, while the nylon strap offers lightweight durability and field-ready comfort.

With 10 bar water resistance, magnetic protection, and a day-date complication, the SBSA141 is a rugged yet refined option for those who live with adventure in mind.

Built for reliability and style, this is a must-have for fans of military design, mechanical movements, and affordable Japanese quality. A perfect daily driver with character.
