What people say

Owners + reviewers, side by side

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

Second Hour Giant Stride

The Silietta SW200 movement is a strength. The price point relative to other microbrand super compressor options is a weakness.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.

From video reviewers

The Spinnaker Dumas GMT offers robust build quality for its price point. Reviewers noted the 300-meter water resistance.
