What people say

Owners + reviewers, side by side

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

Tudor Black Bay 58 GMT

The Tudor Black Bay 58 GMT is widely praised for its functional, proportional, and ergonomic design, wearing identically to the standard Black Bay 58 and feeling substantial without being oversized. Owners are very happy with the 39mm case proportions, noting an improved 12.8mm height. The gilt dial aesthetics and gilt-effect accents are a point of praise for some, while others find them divisive. The Tudor Black Bay 58 GMT features the METAS-certified MT5450-U movement, which is anti-magnetic to 15,000 Gauss and offers a 65-hour power reserve. On balance, owners and reviewers rate the Tudor Black Bay 58 GMT highly for its improved case proportions and gilt dial aesthetics.

From video reviewers

The comfortable 39mm case size is a significant strength. The value at its price point is also a shared positive. Reviewers did not reach a consensus on any weaknesses.

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.

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.
