Owners + reviewers, side by side

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

Islander Calabro GMT World Time Automatic Watch with Anthracite Dial #ISL-316

Islander Calabro GMT World Time Automatic Watch with Anthracite Dial #ISL-316 offers excellent value at $329 MSRP, featuring a handsome anthracite dial with applied indices, a sapphire crystal, and a quality 120-click unidirectional bezel. Owners highlight the NH34 movement and well-proportioned 40x48x20mm case. Overall, owners rate the Islander Calabro GMT World Time Automatic Watch with Anthracite Dial #ISL-316 highly for its value and feature set at the price point.

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.
