What people say

Owners + reviewers, side by side

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

Seestern S446 GMT

Owners widely praise the Seestern S446 GMT for its stunning finishing and extreme value, with a sapphire crystal and adjustable clasp. The winding action is noted as buttery smooth, and the 39.5mm case size is considered very wearable. Some owners, however, flag the lume as a weak point and one owner found the bracelet clasp lacked sufficient micro-adjustment. The Seestern S446 GMT is considered an extreme value for the dollar. Overall, owners rate the Seestern S446 GMT highly for its exceptional finishing and value proposition at its price point.

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.
