SEIKO PROSPEX SRPL53K1

Celebrate the beauty of the ocean with the Seiko Prospex SRPL53K1, a special edition automatic dive watch forged in partnership with PADI (Professional Association of Diving Instructors). Housed in a sharply angled 41.7 mm stainless steel case, this model is defined by its breathtaking emerald-green gradation dial, specifically textured to echo the shimmering, rippling surface of water illuminated by sunlight. Measuring 12.3 mm thick with a 49.5 mm lug-to-lug distance, the watch wears with exceptional balance on the wrist. A highly legible layout is achieved through generous LumiBrite application across the broad hands, indices, and unidirectional rotating bezel, all protected by Seiko’s durable Hardlex crystal. The robust stainless steel bracelet is securely fastened by a three-fold clasp equipped with a secure lock, push-button release, and a practical diver’s extender.

Beneath the special edition case back lies the trusted Seiko Caliber 4R35, an in-house mechanical movement featuring 23 jewels, manual winding capabilities, and a hacking seconds function for precise time setting. Fully wound, the engine provides approximately 41 hours of reliable power reserve. Built as a true tool watch for marine exploration, the SRPL53K1 adheres to strict ISO 6425 diving standards with a 200-meter water resistance rating and safeguards its timekeeping with 4,800 A/m of magnetic resistance. Weighing 170 grams, it perfectly balances a striking, nature-inspired aesthetic with unwavering professional-grade performance.
