Thank you for viewing. When engaged in missions such as rescue operations, the direction, which is important information, can be measured with a single push of the large button on the 3 o'clock side. Temperature measurement and display are also possible by pressing the button on the 4 o'clock side, and we have focused on operability so that directional measurement can be performed intuitively without visual confirmation even in harsh conditions. The buttons employ a button guard cylinder structure that enables dust and mud resistance. The cylindrical pipe that protects the button and the gasket built into the button prevent the entry of fine sand and mud. In addition, the cylindrical pipe plays a role in mitigating the impact received by the button and improving operability, making it a specification that can withstand tough use. To improve visibility, wide hour and minute hands, and large Arabic numeral indexes are used at the 12, 3, 6, and 9 o'clock positions. A sprocket-motif disc hand is used for the mode display, and the band has a texture that gives the impression of a non-slip surface, resulting in a design full of military taste throughout. This is a Mudmaster that supports tough men who are on harsh missions on land. It has a used feel, but I think it will still be active. The battery was replaced in February of this year. Thank you.
