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.

Horage Omnium K2

The Horage Omnium K2 is lauded for its slim 7.95mm profile and chronometer-certified K2 micro-rotor movement with a 72-hour power reserve. Reviewers note its technical innovation, including a proprietary silicon escapement and modular K1 movement, and praise its value. However, some find the molded, luminous hour numerals too whimsical, and the explicit mention of "silicon escapement" on the dial is considered unnecessary. On balance, reviewers rate the Horage Omnium K2 highly for its technical innovation and slim profile at its price point.
