Formex Reef GMTvsSeiko Presage Classic Series “Craftsmanship” Enamel Dial
The numbers, the dial colors, the calibers — laid out so you can stop flipping between tabs.
Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
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.
Owners and reviewers widely praise the Seiko Presage Classic Series “Craftsmanship” Enamel Dial for its high-quality, handcrafted enamel dials, with specific commendations for the depth and subtle gloss of urushi lacquer and the excellent legibility of minimalistic markers and contrasting hands. The watches are frequently cited as offering significant value, with one reviewer noting the SPB163 as a great value at €1,300, and another highlighting the series' impressive 100M water resistance and Japanese design inspiration at $1,300 USD. However, the 12.4mm to 12.8mm thickness is noted by multiple sources as a potential area for improvement, with a preference for under 12mm, and one owner dislikes the date window. Accuracy figures for the 6R27 movement range from -15 to +25 seconds per day, and its power reserve is closer to 35-40 hours than the advertised 45 hours.
