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.

Zelos Vitesse

Owners widely praise the Zelos Vitesse for its vintage motorsport design and striking dial options, with particular appreciation for the salmon and panda configurations and their finishing. The bracelet, clasp, and overall value at $1200 are frequently highlighted as strong points. Some owners note the watch sits high on the wrist, and a few have observed minor cosmetic imperfections on subdials. The La Joux Perret L100 movement's accuracy varies, with one report of +5 seconds per day, and several owners find the winding action stiff and noisy, the pushers sticky, and the screw-down crown's feel underwhelming. On balance, owners rate the Zelos Vitesse highly for its captivating dial and strong value proposition, despite some reservations about the chronograph's operational feel and case height.
