Zelos Hammerhead 43 Field

However, some owners feel the 43mm case wears large, suited for wrists 7.5 inches and up, and a reviewer notes its substantial 17mm thickness. The rubber strap is disliked for making the watch feel top-heavy, and the date window is considered tiny and hard to see. Some owners express disappointment with the NH movement. Overall, owners and reviewers rate the Zelos Hammerhead 43 Field well for its distinctive design and dial appeal at its price point.
