What people say

Owners + reviewers, side by side

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

Henry Archer Tidslinje

Owners widely praise the Henry Archer Tidslinje for its superb build quality, captivating dial designs, and comfortable wearability, with many highlighting its 40mm size and 12.1mm thickness as very wearable. The triple date function is appreciated for its utility and collection variety, and the beads of rice bracelet is frequently noted for its comfort and quality. Accuracy figures vary, with some owners reporting +/- 2-4 seconds per day and others around 10-15 seconds per day as advertised. Some owners find the day/month indicators and the numbering for days of the week to be tiny and hard to read, and the black bezel is considered disproportionately large and cosmetic by some. One owner noted disappointment that a micro-adjust clasp is no longer offered on the Lunaris model. Overall, owners rate the Henry Archer Tidslinje highly for its captivating design and excellent value for money.

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.
