What people say

Owners + reviewers, side by side

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

Ferro Time Master 70

The Ferro Time Master 70 is praised for its distinctive 1970s-inspired polygon case and visually striking silver dial with orange accents and unique lume colors. Owners appreciate the retro design with unique touches, clean dial, and lumed markers, along with the smooth winding of the Miyota 9039 movement. Its 39mm diameter, 10.4mm thickness, and 47mm lug-to-lug dimensions contribute to comfortable wearability, further enhanced by a well-executed faux-single link bracelet featuring a practical on-the-fly micro-adjustment clasp. On balance, owners and reviewers rate the Ferro Time Master 70 highly for its retro design and comfortable wearability.

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.
