What people say

Owners + reviewers, side by side

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

Studio Underd0g Project Passion Crew

The Studio Underd0g Project Passion Crew is noted for its unique "coarse dégradé amber and royal purple" multi-layer dial and manual-wind Sellita SW510 M chronograph movement with a 63-hour power reserve. However, its accessibility is severely limited as it is only sold as a $64,900 set with another watch. Overall, reviewers highlight the distinctive dial and chronograph movement as key features, though the high price and bundled sale significantly restrict its availability.

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.
