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 SPIRIT PILOT FLYBACK

The Longines Spirit Pilot Flyback is widely praised for its refined 39.5mm case size, improved wearability, and clean dial design, incorporating enthusiast feedback by removing the five stars and date. Reviewers and owners consistently highlight its exceptional finishing, well-acting ceramic bezel, and the value it offers. The manual-winding L792.4 column-wheel chronograph movement is COSC-certified and offers a power reserve of approximately 68 to 72 hours. Some owners expressed disappointment with the removal of the five stars from the dial, and one reviewer noted that some numerals are partially cut off by the subdials. The watch is priced around $5,350 to $5,550 USD. Overall, owners and reviewers rate the Longines Spirit Pilot Flyback highly for its improved dimensions, finishing, and value proposition.
