Design and Build Quality
The SARX45K1 presents a muscular yet balanced profile, with a 45 mm case that suits larger wrists without overwhelming smaller ones. The black dial with applied indices and Super-LumiNova markers ensures excellent legibility in low light, while the ceramic bezel insert resists scratches and retains its appearance over time.
Protected by a Hardlex crystal and seated in a sturdy stainless steel case, the watch meets Seiko’s rigorous standards for diver’s watches. The screw-down crown and case back enhance water resistance, and the included Diver 200m Pro Bracelet offers solid lug-to-lug comfort and secure deployment with the diver’s 200m lock clasp.
Movement and Performance
Automatic Caliber 7R65 Highlights
At the heart of the Prospex X Diver 200m Chronograph is the Caliber 7R65, a robust and serviceable automatic movement with a 41-hour power reserve. The column wheel chronograph mechanism provides smooth start, stop, and reset operation, making it reliable for timing dives or surface intervals.
Rated at 21,600 vibrations per hour with four jewels, the movement accommodates the added complexity of the chronograph while maintaining solid accuracy. Catawiki’s listing typically includes service history and photos of the movement, helping you confirm its condition before bidding.
