What people say

Owners + reviewers, side by side

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

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.

Wolbrook Skindiver II Professional

Owners widely praise the Wolbrook Skindiver II Professional for its comfortable wearability, long-lasting lume, and attractive dial designs, with some appreciating the quartz accuracy and smooth sweeping second hand. The watch features a 40mm diameter, a well-weighted 120-click unidirectional countdown bezel with a BGW9 lumed triangle, and a shock-resistant HexapleX case architecture. It is powered by either a Miyota 9015 or 8315 movement, with the latter adjusted in France to ±15 seconds per day and offering a 60-hour power reserve. Some owners find the 20mm strap potentially problematic and note it wears like a 42mm watch despite its 40mm case size. One reviewer expressed disappointment in hand color matching, poor lume, bezel wobble, and the watch sitting high on its strap, ultimately not recommending it.
