What people say

Owners + reviewers, side by side

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

Cincinnati Watch Company P-40 A-11 Pilot Black Automatic

Owners widely praise the Cincinnati Watch Company P-40 A-11 Pilot Black Automatic for its sharp finishing, textured pearlescent dial, and excellent lume. The simple, understated design and comfortable 38mm size are also frequently highlighted. Some owners note the bracelet lacks quick micro-adjustments and the quick-release spring bars can dig into the wrist. One owner found the lume blocks potentially thinner and the font on larger numbers less desirable than a standard typeface, though the seconds hand was considered a success. Overall, owners highly recommend the Cincinnati Watch Company P-40 A-11 Pilot Black Automatic for its great craftsmanship and value.

Formex Reef GMT

The Formex Reef GMT is widely praised for its unique porthole case shape, COSC-certified Sellita SW330-2 movement with good finishing, and comfortable quick-release bracelet with on-the-fly micro-adjustment. Reviewers note its robust construction, impressive specifications, and strong value proposition, with a slim 11.4mm profile accommodating 300m water resistance and an exhibition caseback. However, owners widely report the 53mm lug-to-lug span with male endlinks makes it too large for smaller wrists. Some find the bezel action stiff and potentially slippery, and a reviewer desired sharper finishing and edges, deeming the aesthetic too modernist. The GMT variant sacrifices a timing bezel unless swapped, and one owner notes sharp edges on the crown and crown guard. Overall, owners and reviewers highly rate the Formex Reef GMT for its exceptional value and well-executed features, particularly its bracelet system and COSC-certified movement.

From video reviewers

The watch features a COSC-certified SW330-2 GMT movement, which is visible through a sapphire crystal display case back and beautifully decorated. The watch's water-resistance of up to 300m/1000ft is a notable feature. The 42mm diameter may be too large for smaller wrists.
