What people say

Owners + reviewers, side by side

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

Lorier Neptune SIV

Owners widely praise the Lorier Neptune SIV for its versatile, vintage-inspired design featuring a glossy gilt-style dial and a comfortable, tapered bracelet, noting its affordability reduces wear anxiety. Reviewers and owners alike mention the acrylic crystal as a point of contention, with some preferring sapphire, and one owner finds the bracelet lacks the feel of more expensive options. On balance, owners and reviewers rate the Lorier Neptune SIV highly for its appealing vintage aesthetic and value proposition.

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.
