Seiko Explotilus NOS RARE Nautilus SNKK61 Rare Automatic Mens Watch

The Seiko SNKK61 (7S26-03R0) is a 38mm men’s automatic watch with a stainless steel case and a black analog dial protected by hardlex crystal.

The case of the SNKK61 measures approximately 38mm wide (not including the crown) by 12mm thick and is water resistant to 30 meters. This should be sufficient for splashes & rain, The stainless steel bezel is fixed (cannot be rotated). The gap between the lugs is 20mm and the bracelet band can be adjusted to fit

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 should run for up to 43 hours when fully wound and will self-wind when moved.
