What people say

Owners + reviewers, side by side

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

Gruppo Gamma Vanguard Weathered

The satin-finished steel case is well-executed and aesthetically pleasing. The watch's lumières de nuit are not particularly bright, which might be a drawback for some users. Reviewers disagree on the watch's originality, with one reviewer finding it pleasing in-person and another describing it as decidedly derivative.

Zelos Hammerhead V3 300m Bronze

Owners widely praise the Zelos Hammerhead V3 300m Bronze for its distinctive 70s-inspired design, slim 13.5mm case, and improved lume, offering a sophisticated timepiece at an accessible price point starting at $349. The unique dial is noted for evoking an otherworldly feeling, and the comfortable bracelet features on-the-fly micro-adjustment. Some enthusiasts express frustration with shipping delays and a desire to see the watch on a wrist before purchase. One owner flags that the clasp material could be more scratch-resistant, and resizing bracelet pins can be stubborn. On balance, owners rate the Zelos Hammerhead V3 300m Bronze highly for its unique design and build quality at its price point.
