What people say

Owners + reviewers, side by side

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

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.

Straton Syncro - Green, Purple and Red

Owners praise the Straton Syncro's automobile-inspired design and practical features like a clear date window and 200m water resistance. The domed sapphire crystal is a pleasing aesthetic element, and the 44mm case is comfortable and balanced despite its 14.9mm thickness. However, some find the fully lumed dial's milky appearance and cool tones detract from legibility, alongside harsh case angles and busy bezel markings. The standard Milanese bracelet's polished finish contrasts with the brushed case and features an outdated clasp. One owner feels the watch is overpriced at nearly $500 for its Seiko VK64 movement. Overall, owners appreciate the Straton Syncro's unique design and robust build, though some question its value proposition and find certain design elements compromise legibility.
