What people say

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 ULTRA-CHRON CLASSIC

The Longines ULTRA-CHRON CLASSIC is widely praised for its high-beat 5Hz movement, offering superior accuracy and a smooth seconds hand, with reviewers noting its TIMELAB certification for chronometer standards. Owners and reviewers alike commend its faithful retro design, capturing beloved 1960s details with modern relevance and a charming appearance. The bracelet is described as comfortable and refined, featuring a micro-adjustment clasp, and the sunray silver dial with sparkling indices is a notable strength. Some owners, however, find the 11mm thickness detracts from a vintage feel, and there is a desire for a no-date version. The 40mm case wears larger than expected, with many suggesting the 37mm version offers superior wearability and fit for most wrists, and its 50m water resistance is considered not exceptional. Overall, owners and reviewers rate the Longines ULTRA-CHRON CLASSIC highly for its accurate high-frequency movement and successful retro design at its price point.

From video reviewers

The watch's high-beat movement, certified by TimeLab Geneva as an Ultra-Chronometer, is a notable feature. The relatively high price compared to its competitors is a drawback. Reviewers disagree on the optimal case size, with one reviewer mentioning 41mm and 43mm, and the other mentioning 37mm and 40mm.
