What people say

Owners + reviewers, side by side

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

Oak & Oscar The Humboldt GMT

Oak & Oscar The Humboldt GMT owners widely praise its exceptional accuracy, often running at or near 0 seconds per day, and its comfortable wearability with subtle design details. The construction quality for the price point, sandwich lume, and anti-magnetic properties are also highlighted. Some owners find the bracelet sizing adjustment slightly awkward, and one noted the lume could be brighter. Overall, owners rate the Oak & Oscar The Humboldt GMT highly for its accuracy and comfortable wearability.

Phoibos Leviathan

Owners widely praise the Phoibos Leviathan for its excellent value, superb case finishing, and generous lume. The watch is described as visually striking, legible, and well-made, with a unique case design, sapphire crystal, and a comfortable FKM strap or excellent bracelet with a milled clasp and quick adjustments. Some owners note the bezel's staggered jimping can cause fingers to slip, and the beveled crystal can distort the view of indices. Accuracy varies, with one owner reporting losing 5-10 seconds per day without a winder, while others state it keeps accurate time out of the box. The watch is frequently described as heavy and thick, with some owners finding it too large for wrists smaller than 7.5 inches, although newer models feature an improved clasp for better comfort and functionality. Overall, owners rate the Phoibos Leviathan highly for its striking design and impressive finishing at an accessible price point.
