What people say

Owners + reviewers, side by side

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

Baltic Scalegraph Classic

Owners widely praise the Baltic Scalegraph Classic for its stunning retro racing design, detailed dial, and 39.5mm case size, with many finding it offers excellent value. However, some owners report issues with finishing and fit, describing the watches as light or "toylike," while others find the finishing comparable to higher-end brands. Reviewers and owners alike criticize the screw-down chronograph pushers as finicky and impractical, especially given the 100m water resistance which some feel is conceptually incongruent with its rally timer purpose. One owner experienced misaligned bezel markers and moisture ingress after pool use, leading to a return. On balance, owners and reviewers value the Baltic Scalegraph Classic's aesthetic and value proposition, though practical usability concerns regarding the chronograph pushers and isolated quality control issues are noted.

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.
