The Seiko SNK639 (7S26-02E0) is a 38mm men's automatic watch with a stainless steel case and a black analog dial protected by hardlex crystal. It uses a 7S26 caliber self-winding mechanical movement that cannot be manually wound or hacked (the second hand does not stop when the crown is pulled out). It ticks 6 times per second which gives the second hand a smoother movement than quartz watches which tick once per second. The watch will run for up to 43 hours when fully wound and will self-wind when moved.

Personal Comments:
The watch case is in excellent condition with common hairline scratches seen. The watch dial and hands are free from any signs of ageing. A brand new crystal has been installed for clarity. The watch comes on its original bracelet that fits up to 7.25".
