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 Desk Diver Professional Dive Watch Black & Orange

Owners praise the Cincinnati Watch Company Desk Diver Professional Dive Watch Black & Orange for its comfortable feel on the wrist and vintage aesthetic, with one owner stating the brand "crushed it with this one." This model is a re-imagining using NOS Swiss-made cases from the 1970s, featuring a 40x43mm size, a black sunburst sandwich dial, and orange X1 Superluminova indices and hands. It is equipped with a Sellita SW-210 handwound movement, has 0m water resistance, and a friction-fit bezel with metallic orange markings. On balance, owners rate the Cincinnati Watch Company Desk Diver Professional Dive Watch Black & Orange highly for its unique vintage character and comfortable wearability.

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.
