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 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.
