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 39.5 mm

The Formex Reef 39.5 mm is widely praised for its refined finishing, comfortable and well-proportioned case design, and impressive specifications for its price point, including COSC-certified Sellita SW300-1 movement and 300m water resistance. Owners and reviewers highlight the tool-less micro-adjust clasp and quick-release spring bars as practical features. Some reviewers note that the 22mm lug width feels slightly disproportionate to the smaller case, and the bracelet could benefit from more taper, though this is a point of contention for some owners who value the overall package. A prototype crown protrusion issue is noted as being addressed for production. On balance, owners and reviewers rate the Formex Reef 39.5 mm highly for its excellent value and well-executed design.

Vario 1918 SG60 Merlion Trench

The Vario 1918 SG60 Merlion Trench is widely seen as a commemorative keepsake, particularly for those celebrating Singapore's 60th anniversary or born in 1965. Reviewers note its vibrant red enamel dial and 37mm steel case with fixed wire lugs, along with 100m water resistance. One owner reported the watch is "patina-ing well" after three years, and the Miyota 82S5 movement is considered a reliable, cost-effective base. Overall, owners and reviewers appreciate the Vario 1918 SG60 Merlion Trench as a unique souvenir and tribute piece, with its distinctive enamel dial being a key draw.
