What people say

Owners + reviewers, side by side

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

Longines PrimaLuna Moonphase

The Longines PrimaLuna Moonphase features a fluid case design and a 72-hour power reserve from its automatic movement. Owners note its accuracy averages 1.3 seconds lost per day across six positions, and 3 to 4 seconds on the wrist, performing within COSC standards. Previously, moon phase models utilized quartz movements, a detail that may not appeal to mechanical watch enthusiasts. Overall, owners rate the Longines PrimaLuna Moonphase highly for its updated automatic movement and reliable timekeeping.

Spinnaker Croft

Owners and reviewers widely praise the Spinnaker Croft for its vibrant dial colors, chunky hands and bezel, and overall value, with one owner noting the Miyota 8218 movement and cyclops as appreciated features. Reviewers flag the bracelet and clasp as budget-friendly limitations, citing friction-fit pins, sharp edges, and a stiff security lock. On balance, owners and reviewers rate the Spinnaker Croft highly for its accessible skeletonized dive watch aesthetic and appealing design at its price point.
