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.

Zelos Skyraider 40 Skeleton

The Zelos Skyraider 40 Skeleton is noted for its skeletonized dial and the use of BGW9 and C3 Super-LumiNova for legibility. It is powered by a manual-wind ETA 6498 movement, offering a 44-hour power reserve. On balance, the Zelos Skyraider 40 Skeleton is seen as a cool-looking option, though availability is a factor.
