What people say

Owners + reviewers, side by side

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

Seiko Essentials Chronograph

Owners find the Seiko Essentials Chronograph beautiful for its price, particularly on the grey market, praising its lightweight wearability for active use and college budgets. One owner notes the orange stripe on the stopwatch button can expand and fall off in heat. The watch is 41mm and was purchased for $160. On balance, owners rate the Seiko Essentials Chronograph highly for its aesthetic appeal and value, especially for active wear on a budget.

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.
