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 Thresher 44

Owners widely praise the Zelos Thresher 44, with one owner noting its finish has proven remarkably scratch-resistant. However, one owner found the finishing on their hammered grey variant not as well done as expected. The Zelos Thresher 44 with an agate dial sold out in 90 seconds, with one owner receiving theirs and noting the bracelet was fully wrapped. Overall, owners rate the Zelos Thresher 44 highly for its desirability and scratch-resistant finish.
