This is a Japan Ground Self-Defense Force model from Kentex, a Japanese military watch brand. It's a popular chronograph model that combines practicality and design. The military-inspired color scheme of a dark green dial combined with a black case offers high visibility and is suitable for a wide range of uses, from daily wear to outdoor activities. Despite its rugged construction, its understated design makes it easy to incorporate into any outfit. This is a practical professional model born from the demands of soldiers in harsh environments. The entire watch features a black IP coating for a stealthy design that minimizes light reflection. Furthermore, the top glass is a special specification using K1 super-hard glass with a light smoke processing, enhancing both practicality and functionality. An aftermarket replacement NATO strap is included, allowing you to change it according to your needs and style.
