The Zelos Hammerhead V3 Ti Chalk Blue is a fantastic titanium diving watch. The specifications of the watch are impressive. To start, the case and bracelet are both made from high quality titanium, making this as lightweight as it possibly could be. 

Under the hood you will find an automatic Seiko SII NH35 movement. This is a reliable Made in Japan movement, that hacks and can be wound be hand. The Hammerhead has pretty much anything you can wish for: a comfortable titanium bracelet with quick adjust clasp, 300m water resistance, double domed sapphire crystal with an AR-coating and Superluminova. The case itself is 44mm, but the 48mm lug to lug distance ensures it will fit most wrists.
