Reviews

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

Islander Calabro GMT World Time Watch

Owners widely praise the Islander Calabro GMT World Time Watch for its excellent value and quality, with many appreciating the attractive split dial design and the "true" GMT functionality powered by the Seiko NH34 automatic movement. Specific positive points include the retro day window, a well-regarded bracelet with screw links and micro-adjustments, and applied indices. One owner noted the watch is 39mm, not 40mm, and found the lume not as advertised, while another suggested improvements to the busy dial layout. On balance, owners rate the Islander Calabro GMT World Time Watch highly for its impressive feature set and design at its affordable price point.

Phoibos Leviathan

The Phoibos Leviathan is widely praised for its superb case finishing, generous lume, and original design elements, offering excellent value. Owners consistently highlight the quality of the bracelet, including its milled clasp with quick adjustments and on-the-fly microadjustment on newer models, and the visually striking, legible dials. Some owners find the watch heavy and large, with one suggesting a smaller 37mm or 38mm case size would be ideal, and others note the stock rubber strap can be thick and sticky. Accuracy varies, with some reporting it keeps accurate time out of the box, while others note a loss of 5-10 seconds per day without a winder. The bezel's jimping is also flagged as potentially causing fingers to slip. On balance, owners rate the Phoibos Leviathan highly for its robust build, excellent finishing, and desirable features at an accessible price point.

From video reviewers

The case finishing and bezel action are praised. The bracelet, particularly the clasp, is identified as an area for improvement. Reviewers are split on the watch's wrist presence, with some noting its improved 40mm size and others describing it as having a "beast"-like presence.
