Overview
This 39mm Seiko combines classic steel aesthetics with mechanical reliability. Beneath Hardlex mineral glass lies a black, easy-to-read day-date dial, powered by the 24-jewel automatic caliber 4R36 with approximately 41 hours of power reserve. 10 ATM water resistance makes the watch ready for everyday splashes and swimming, while the transparent caseback lets you see the movement at work. A clean, timeless design that suits both suits and casual occasions.
Comfort
The case dimensions provide a nice balance: 39 mm in diameter, 13 mm high and 48 mm lug-to-lug, the watch rests flat and slides easily under the cuff. The 20 mm wide articulated steel bracelet follows the wrist softly and keeps the 147 grams evenly distributed. Smooth edges and a flat case back reduce pressure points, so the watch feels stable during commuting, work and evening activities - day after day. The bracelet is easily adjusted for a precise fit.
