Formex Reef GMTvsYema Navygraf Heritage

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.

Owners widely praise the Yema Navygraf Heritage for its comfortable 39mm wearability and faithful 1970s reissue design, noting craftsmanship better than expected. Some owners report quality control issues including bezel free play and misalignment, while others find the bezel very tight to turn despite precise 120 clicks. The in-house MBP2000 movement is noted by some to be loud and run approximately +10 to +15 seconds per day. On balance, owners appreciate the Yema Navygraf Heritage for its retro aesthetic and comfortable sizing, with noted concerns around movement accuracy and bezel action.
