What people say

Owners + reviewers, side by side

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

Beaufort Aerotimer

Owners widely praise the Beaufort Aerotimer for its handsome, high-contrast salmon dial and museum-quality finishing, creating a sharp dress field watch with excellent legibility and a crisp California dial. One owner notes the power reserve is closer to 30-34 hours than advertised and finds the 11.45mm thickness slightly noticeable, while another would change the strap. Lume on the 3 and 9 o'clock markers is reportedly poor. Overall, owners rate the Beaufort Aerotimer highly for its vintage style and beautiful craftsmanship at its price point.

Yema Diver

One owner reported a water ingress issue on their Yema Diver the first time it got wet in a lake, despite rinsing and inspecting the watch and bezel. Another owner notes this manual wind Yema Diver has a cool patina but is unlikely to be waterproof or gain value. Overall, owners view the Yema Diver as a fun second watch rather than an investment.

From video reviewers

The Swiss Sellita movement is a notable feature. Reviewers did not reach a consensus on any weaknesses.
