What people say

Owners + reviewers, side by side

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

Marathon Jeep Willys SSGPQ

The Marathon Jeep Willys SSGPQ is a vintage-inspired sports watch with a handsome dial honoring military heritage and a unique case shape. It features a 41mm stainless steel case with a matte parkerized finish, a sapphire crystal, and a MaraGlo luminous dial, powered by an ETA F06.402 quartz movement. Reviewers note that its longer lugs may extend past smaller wrists and the included leather strap is fragile. The Marathon Jeep Willys SSGPQ is available for $500 to $650 USD. On balance, reviewers find the Marathon Jeep Willys SSGPQ to be a good value, particularly for vintage Jeep enthusiasts, due to its design and heritage-inspired dial.

From video reviewers

The 41mm case size is a shared strength. Reviewers noted the bracelet clasp lacks micro-adjustments.

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.
