What people say

Owners + reviewers, side by side

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

Lorier Merlin

Owners widely praise the Lorier Merlin for its vintage-inspired 37mm case, heat-blued hands, raised numerals, and hesalite crystal. The watch is noted for its comfortable wear, with some finding it wears large despite its size and even thinner on a two-piece strap. Drilled lug holes and a locking bezel are also appreciated features. Accuracy varies, with one owner reporting +8 seconds per day, while others do not specify. Some owners find the dual-crown design unappealing or the case chunky, with the 37mm size feeling small for a dive bezel watch, though others find it perfect for smaller wrists. The supplied strap and its hardware are considered cheap by one owner, and the bezel action is described as light and hollow. A desire for a sapphire crystal option at the price point is mentioned by some, while others prefer the hesalite for its vintage look. On balance, owners and the community rate the Lorier Merlin highly for its authentic vintage aesthetic and comfortable wear.

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.
