What people say

Owners + reviewers, side by side

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

Phoibos Narwhal

Owners widely praise the Phoibos Narwhal's 38mm size and slim 11.5mm height for a 200m diver, noting it wears well on smaller wrists and its case shape resembles an integrated bracelet. The aventurine and Howlite dials are described as captivating, and some appreciate the contrast finishing and retro looks. However, some owners criticize misaligned markers and a tilted date window, with one owner finding the hands thick and popsicle-style. The value proposition is debated, with some finding it a good buy at $390 but others considering $480-$490 too much due to a slabby design and difficult-to-size bracelet. On balance, owners find the Phoibos Narwhal appealing for its design and wearability, though quality control and pricing are points of contention for some.

From video reviewers

The unique stone dial is a significant strength. The bracelet's refinement is a weakness. Reviewers disagree on the dial's appeal, with one highlighting its sunburst effect and applied indices, while another focuses on the natural stone variation.

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.
