The Zelos Hammerhead Titanium Submarine is a very cool watch. The specifications of the watch are very impressive. To start, the dial is made from steel coming from an actual US submarine. The case and bracelet are both made from lightweight titanium. 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 divers extension, 1000m water resistance, a ceramic bezel, domed sapphire glass with an AR-coating and C3 and BGW9 lume. The watch itself is very comfortable. The case itself is 44mm, but the 49mm lug to lug distance ensures it will fit most wrists, especially with the reduced weight compared to the steel and bronze versions.
