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.

Longines MASTER COLLECTION

The Longines Master Collection is widely praised for its excellent value, beautiful dial execution featuring engraved Breguet numerals and snailed subdials, and classic, vintage styling. Owners and reviewers highlight its dressy and thin profile, with one owner noting its versatility as a daily wear. The Master Collection offers complications like chronographs and moon phases at competitive price points, with some finding the case finishing homogenous and the pushers to feel cheap. Accuracy figures are not consistently reported across sources, but one owner notes a broken moon phase setting mechanism requiring professional service. Water resistance is considered light at 30m, and the bracelet lacks micro-adjustments. Overall, owners and reviewers rate the Longines Master Collection highly for its dial execution and value, particularly when purchased below retail.
