What people say

Owners + reviewers, side by side

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

Praesidus DD-45

The Praesidus DD-45 is lauded for its detailed vintage-inspired design and solid finishing, with reviewers highlighting the impressive aged indices and hands on the "Patina" version and a well-finished 38mm steel case. Its 100-meter water resistance exceeds that of the original military watches, and the included leather strap is praised for its quality and vintage character, despite initial stiffness. One reviewer notes the Landeron movement exhibits jerky hand-winding. Overall, reviewers rate the Praesidus DD-45 highly for its faithful vintage aesthetic and robust build at its $900 price point.

Longines PRIMALUNA

Owners widely praise the Longines PRIMALUNA for its attractive style and understated 26.5mm size, with the automatic version favored for its smooth sweep. The redesigned 34mm model features a fluid, polished case, available in steel or bi-metal, with dial options including mother-of-pearl. The automatic movement, Caliber L899, demonstrates consistent accuracy averaging a loss of 1.3 seconds per day across six positions and 3-4 seconds per day on the wrist, performing within COSC standards. The automatic movement offers a 72-hour power reserve. On balance, owners and reviewers highly regard the Longines PRIMALUNA for its blend of classic aesthetics and contemporary design updates, particularly appreciating the automatic movement's performance and the watch's overall stylish appeal.
