What people say

Owners + reviewers, side by side

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

Glycine Airman No. 1 GMT

Owners widely praise the Glycine Airman No. 1 GMT for its historical significance and attractive dial. However, some find the 36mm case size to be a bit small, and the GMT hand can be difficult to distinguish from the minute hand. The watch has a very limited 3ATM water resistance. Later versions feature sapphire crystals, differing from earlier plexi models. Overall, owners value the Glycine Airman No. 1 GMT for its historical appeal and dial design, despite minor legibility and sizing concerns.

From video reviewers

The case finishing and dial colors are praised. The value proposition is tied to a sale price, with questions about long-term competitiveness.

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.
