The Zelos Hammerhead V3 Crimson Red is a very cool watch. The specifications of the watch are impressive. 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 metal bracelet, 300m water resistance, double domed sapphire glass with an AR-coating and C3 X1 and BGW9 lume. The case itself is 44mm, but the 48mm lug to lug distance ensures it will fit most wrists.
