Featuring a satin-finished dark anthracite watch case, the OPS marks the revival of a model cherished by numerous Navy Forces in the 1960s. The gracefully domed sapphire box glass, complete with an internal anti-reflective coating, enhances its stylish presence on the wrist, making it suitable for diverse occasions—from the depths of the sea to complementing your laptop. Its ideal 40 mm size and 13.5 mm height make it versatile for any event and wrist size. With a water resistance of up to 20 bar (approximately 200 m depth) and powered by the high-quality Swiss Mantramatic MM01 movement, derived from the top-tier Sellita SW200-1, this timeless design has been fully modernized to meet today's standards.
