What people say

Owners + reviewers, side by side

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

Citizen Series 8 880 GMT Gold-Tone

The gold-tone Citizen Series 8 880 GMT features a "Root Beer"-like color scheme with a gradient white-to-black dial and gold accents, inspired by the Tokyo skyline. Reviewers note its chunky, angular case silhouette with short lugs and a bracelet with two shades of ion-plated gold. The bidirectional bezel has a serrated edge and clicks hourly, featuring a blue and black 24-hour scale. It offers GMT functionality with an independently jumping local hour hand and 100 meters of water resistance, powered by the Citizen 9054 automatic GMT movement. Lume is described as good but not as intense as a dive watch. At its price point, the pin-and-collar bracelet system lacking micro-adjustments is flagged as a drawback. Overall, reviewers highlight the unique color scheme and GMT functionality as key features of the Citizen Series 8 880 GMT Gold-Tone.

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.
