What people say

Owners + reviewers, side by side

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

Grand Seiko SBGX355

The Grand Seiko SBGX355 is widely praised for its beautiful dial, excellent finishing, and perfect 37mm size. Owners report unparalleled accuracy from the 9F62 quartz movement, rated to within 10 seconds per year. The high-intensity titanium case and 100m water resistance are noted features. Some consider the SBGX355 a "baby Snowflake" and a more accessible alternative to other models. Overall, owners and reviewers rate the Grand Seiko SBGX355 highly for its iconic Snowflake dial and exceptional quartz accuracy in a wearable 37mm case.

From video reviewers

The titanium case finishing is a significant strength. The deployant clasp is noted as prone to rattle. Reviewers disagree on the ideal case size for everyday wear.

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.
