What people say

Owners + reviewers, side by side

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

Vaer D4 Meridian Solar

Owners widely praise the Vaer D4 Meridian Solar for its excellent value, citing features like the sapphire crystal with AR coating and its solar-powered quartz movement. The watch's great colorways, unique yet simple design, and gilt hands are frequently highlighted, contributing to its appeal as a sports or outdoors watch. However, the second-hand alignment is a common point of contention, with some owners finding it annoyingly imprecise for the $399 price point, a characteristic the brand states is within normal tolerances. The steel bracelet has also been described as disappointing with sharp edges, though alternative strap options can mitigate this. On balance, owners and reviewers rate the Vaer D4 Meridian Solar highly for its impressive feature set and design at its price point, despite minor criticisms regarding second-hand alignment and the stock bracelet.

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.
