What people say

Owners + reviewers, side by side

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

Hamilton Broadway Auto Chrono

Owners widely praise the Hamilton Broadway Auto Chrono's blue and green dial with carved stripes and applied indices, as well as its combined polished and brushed case finishing. The 80-hour power reserve from the H-30 movement is a noted strength. However, some owners report the lume is less than desirable, with only the hands lumed, and the 42mm case size is considered too large by some. On balance, owners rate the Hamilton Broadway Auto Chrono highly for its distinctive dial and generous power reserve.

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.
