What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Yema Flygraf Bi-Compax French Air Force

Owners widely praise the Yema Flygraf Bi-Compax French Air Force for its attractive, toolish aesthetic and excellent quality for the price, noting the legible Type A dial and 40mm titanium case. However, the acrylic crystal scratches easily, and the titanium case is prone to marking. The mecha-quartz movement's chrono timer sweeps rather than ticks, and one owner questions the purpose of the oversized crown. The in-house Yema 2000 movement is accurate at +/- 10 seconds per day but has a 42-hour power reserve, and some owners express concerns regarding Yema's past quality control and customer service. On balance, owners rate the Yema Flygraf Bi-Compax French Air Force highly for its attractive design and value, despite concerns about material durability and brand service history.

Zelos Hammerhead 43 Field

The Zelos Hammerhead 43 Field is praised for its unique bronze case patina potential, masculine angular design, and fantastic lume. Owners also highlight the lovely Mosaic Ember and purple agate dials. 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.
