What people say

Owners + reviewers, side by side

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

Halios Seaforth IV

Owners widely praise the Halios Sunburst Blue for its perfect 40mm size, stunning sunburst dial, and excellent lume, with one owner calling it Halios's best effort and a potential "Omega AT killer." The ETA 2824 movement is noted as running smoothly, and the watch is considered a great value with strong resale. Some owners desire larger sizes or different dial colors, and one reviewer found the Sinn 556i more versatile. The sapphire bezel is described as tall and flat, which is a point of contention for some. Overall, owners rate the Halios Sunburst Blue highly for its design, size, and value.

From video reviewers

The sunburst blue dial is a standout feature. Limited water resistance is a shared concern.

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.
