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

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.

Yema Navygraf Chrono

Owners praise the Yema Navygraf Chrono for its handsome, versatile design and the value offered by its Valjoux 7750 movement. A reviewer notes the 40mm case's fully polished finish, which some feel clashes with its sporty aesthetic, and mentions its 13.9mm thickness is noticeable. One owner reported wearing the Yema Navygraf Chrono for two months without issues, receiving compliments. On balance, owners and reviewers find the Yema Navygraf Chrono to be a good-looking and well-specced watch for its price.
