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 One 31

Owners widely report the Tudor Black Bay One 31's polished case and bracelet scratch easily, though its wearability under gloves and robust movement are praised. Some desire more micro-adjustment options on the clasp, and a lack of contrast between the silver dial and hands is noted. The 31mm size may be a consideration for daily wear due to its 50-hour power reserve. On balance, owners and reviewers appreciate the Tudor Black Bay One 31 for its comfortable wearability and robust movement, despite concerns about case scratching and clasp adjustability.
