Islander Greenport 39mm Dive Watch with Black and White Dial #ISL-300

The Islander Greenport 39mm Dive Watch with Black and White Dial #ISL-300 is praised for its 39mm size and comfortable fit, with its bi-directional dual time bezel noted as a useful feature for tracking different time zones. Owners appreciate the lumed ceramic bezel and the slightly domed sapphire crystal. One owner specifically highlights the dial layout as a strong positive. The screw-down crown is also mentioned as a nice touch. On balance, owners rate the Islander Greenport 39mm Dive Watch with Black and White Dial #ISL-300 highly for its wearability and functional bezel.

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.
