What people say

Owners + reviewers, side by side

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

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.

Longines PRIMALUNA

Owners widely praise the Longines PRIMALUNA for its attractive style and understated 26.5mm size, with some preferring the automatic for its craftsmanship and heirloom quality. The redesigned 34mm model features an automatic movement, date complication, and polished case design, available in steel or bi-metal with various dial and strap options. Accuracy averages a loss of 1.3 seconds per day across six positions, running 3-4 seconds slower on the wrist, which is within COSC standards. Prices range from EUR 2,850 to EUR 6,600. Overall, owners rate the Longines PRIMALUNA highly for its appealing design and reliable automatic movement.
