What people say

Owners + reviewers, side by side

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

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.

Zelos Spearfish Dual Time

Owners widely praise the Zelos Spearfish Dual Time for its attractive design and the well-executed big date complication. The watch is described as a non-attention-seeking option that looks awesome, with a thickness of 12mm including the crystal and 10mm without. One owner found the $1900 price tag too expensive and uncharacteristic for the brand. On balance, owners rate the Zelos Spearfish Dual Time highly for its attractive design and the well-executed big date complication.
