The Zelos Hammerhead Chrono Steel Midnight Blue is an amazing watch watch. The specifications of the watch are impressive. Under the hood you will find an amazing mechanical Valjoux 7750 Elabore Grade chronograph movement. The Hammerhead has pretty much anything you can wish for: a comfortable rubber strap, 1000m water resistance, double domed sapphire glass with an AR-coating and C3 and BGW9 lume. The case itself is 44mm, but the 48mm lug to lug distance ensures it will fit most wrists.
