The all-black mechanical Seiko watch, known as the "Stealth". The watch is original and has been very lightly used, almost new. Here are most of the watch specifications: • The case is made of stainless steel and coated with a hard carbon layer in a matte black finish. • The dial and bezel are completely black, and the indices and hands are coated with a luminous material, but in a dark gray color to match the "stealth" look. • Strap: The watch comes with a high-quality and very durable black fabric NATO strap, enhancing the watch's sporty and military character, and providing complete comfort for the wrist during daily use. • Movement: The watch operates with a fully automatic movement, caliber 4R36 (relies on your wrist movement to wind). • Power Reserve: The caliber provides a power reserve of approximately 41 hours when fully wound. • Crystal: Seiko's special hardened Hardlex crystal, known for its very good resistance to shocks and scratches in daily use. • Water Resistance: Water-resistant up to 100 meters (10 bar), making it excellent for swimming and daily water activities. • Case Back: A transparent and polished case back allows you to see the movement's gears working.
