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 Bradner GMT

The Spinnaker Bradner GMT is praised for its awesome lume and comfortable wearability, with one owner noting the rubber strap is very comfortable and the beads of rice bracelet fits well on smaller wrists. Some find its 15mm thickness and bold colorway may not appeal to everyone, and one owner views it as more of a casual GMT with tool-watch styling than a diver. Overall, owners rate the Spinnaker Bradner GMT highly for its value and comfortable wearability.
