What people say

Owners + reviewers, side by side

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

Longines CONQUEST HERITAGE CENTRAL POWER RESERVE

The Longines Conquest Heritage Central Power Reserve is widely praised for its beautiful, timeless, 1959-inspired dial and unique central power reserve indicator, with owners considering it a top dress watch in its price segment. Reviewers highlight its balanced layout and contemporary 38mm size, while some owners find the short lugs contribute to a comfortable wear. The watch features a modern 72-hour power reserve movement and is priced at $3,800. One reviewer notes the lugs are not curved enough, potentially creating a gap with the strap, though owners report the alligator strap softens with wear and some find the watch slightly chunky. A potential frustration for some owners is the power reserve indicator not always resetting to the same position when fully wound. On balance, owners and reviewers rate the Longines Conquest Heritage Central Power Reserve highly for its handsome vintage aesthetic and unique power reserve complication at an appropriate price.

Yema Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.
