The U-BOAT Mens Darkmoon 44mm Red Glass 8465/B watch combines a 44mm round shaped stainless-steel case and black rubber strap with a traditional buckle. It has a black analogue dial with luminescent hands which is protected beneath domed scratch resistant sapphire crystal glass. Power is generated by the swiss quartz movement. This model also has a water resistance of up to 50 metres. This watch dial is completely filled with a special oil that emphasizes the dial and creates the illusion of the absence of glass. Watch also features a visible air bubble to compensate the temperature variations. Back of the watch also features a innovative ring locking system that helps for quick battery replacement
