What people say

Owners + reviewers, side by side

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

Boldr Expedition Enigmath

The watch's slide rule function is a convenient feature, allowing for calculations on the go. One potential drawback is the use of the Japanese Miyota 9039 movement, which may be a trade-off for some buyers. Reviewers disagree on whether the quick 'on the fly' adjust bracelet is a more significant advantage than the watch's sapphire crystal for durability and scratch resistance.

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.
