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.

Spinnaker Croft 42 Skeleton

Owners widely report the Spinnaker Croft 42 Skeleton offers good build quality for its price, with some finding it a decent buy on sale. Reviewers note the 42mm case provides significant wrist presence. However, opinions are split on legibility and aesthetics, with some finding it poorly executed and uninteresting while others consider it one of the more legible skeleton watches. The watch is powered by a Seiko NH70 automatic movement with a 41-hour power reserve, though one reviewer considered the movement uninteresting. The bracelet and clasp are considered mediocre for the price point. Overall, owners and reviewers find the Spinnaker Croft 42 Skeleton to be a polarizing but potentially good value skeletonized dive watch when purchased on sale, with its build quality being a key positive for many.
