Titanium, which is lightweight and rust-resistant, is used for the band material, making it suitable for outdoor activities as well as everyday use. The band is treated with black IP, and the case and the liquid crystal part of the dial are also black. The monotone design with a black base provides high visibility and a rugged design. Large Arabic numerals are placed on the three-dimensional dial to improve visibility. Combined with metal parts, it has a valuable finish. The watch's robustness is enhanced by a lightweight and strong glass fiber-reinforced fine resin back cover and a button guard to prevent accidental button operation. The large rotating bezel, which can be operated even with gloves on, gives a wild and robust impression. Case size (H x W x D): 57.5 × 50.8 × 15.8 mm [Management number: 61]
