Seiko - 5 Sports SNZG15 SNZG15K1 SNZG15K Automatic Men’s Watch - Silver and black

The Seiko SNZG15K1 is an automatic field watch featuring a 7S36 movement (non-hacking/non-hand-winding), a legible black dial with LumiBrite, day-date display, stainless steel case, Hardlex crystal, 100m water resistance, an exhibition case back, and a black nylon strap.

• LumiBrite Luminous Application: Seiko's proprietary LumiBrite luminous material is generously applied to the hands and hour markers. This provides excellent and long-lasting glow in low-light conditions, crucial for a field watch.
• Automatic Mechanical Movement (Seiko Caliber 7S36): This watch is powered by Seiko's in-house 7S36 automatic (self-winding) movement. This means it is powered by the natural motion of your wrist and does not require a battery.
• Hardlex Crystal: The dial is protected by Seiko's proprietary Hardlex crystal. This is a toughened mineral glass that offers better scratch resistance than standard mineral glass, though it's not as scratch-resistant as sapphire. It does, however, tend to be more shatter-resistant than sapphire.
• See-Through Case Back (Exhibition Case Back): The watch typically features a transparent case back, allowing enthusiasts to view the automatic mechanical movement in action.
• Recessed Crown at 4 o'clock: A signature design element of many Seiko 5 models. The crown is strategically positioned and recessed at the 4 o'clock position, which enhances comfort by preventing it from digging into the wrist and offers some protection against accidental impacts.
