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.

CWC RN Automatic Divers Watch Mk.2

Owners widely praise the CWC RN Diver for its build quality, comfortable wearability, and classic design with desirable brand heritage, suitable for diving. Some owners consider it a favorite, appreciating its case wear and aging tritium as a classic replacement for previous military issue watches. However, a common complaint across multiple sources is the fixed spring bars, which limit strap options, and some find the watch overpriced for its features, particularly when compared to other military-style watches or when noting specific branding text. One owner wishes CWC offered a smaller diver size. On balance, owners rate the CWC RN Diver highly for its utilitarian capabilities and historical connection, despite concerns about strap versatility and value.
