Seiko Prospex Alpinist SPB155J1 Men's Watch Green • Sapphire Crystal • Automatic Movement Calibre 6R35

The Seiko Prospex Alpinist SPB155J1 is a modern interpretation of the legendary Alpinist line, which dates back to 1959. With its striking dark green dial and polished stainless steel case, the watch combines classic mountaineering design with contemporary watchmaking technology. The 316L stainless steel case measures 38 mm in diameter and is only 12.9 mm thin – a comfortably wearable size that excels both in the field and in everyday life.

Inside beats the tried-and-tested automatic movement Calibre 6R35 by Seiko, featuring manual winding capability, an accuracy of +25/−15 seconds per day, and a power reserve of approximately 70 hours. The curved sapphire crystal with internal anti-reflective coating reliably protects the dial while providing optimum legibility. The date is displayed at 3 o'clock through a magnifying cyclops lens. With water resistance to 20 bar, the watch is well suited for demanding outdoor activities. The stainless steel bracelet with triple-fold clasp and push-button safety completes the robust yet elegant overall impression.
