This is the Bremont ALT1-Z BK black dial chronograph UTC watch. As with all Bremont watches, this model is Chronometer certified and features their Trip-Tick case design with specially treated stainless steel which is seven-times harder than steel used by competitive watch brands. The case measures 43mm and has a sapphire crystal with nine layers of anti-reflective coating on both the top and underside. This is a chronograph model with white subdials which contrast beautifully with the black dial color. There is also a UTC or GMT hour hand allowing the wearer to keep track of a second timezone. The watch is available on a black leather strap or solid-link stainless steel bracelet.
