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.

Boldr Safari

Owners widely praise the Boldr Safari for its attractive dials, robust build with 200 meters of water resistance, and reliable Seiko movements. The California dial design is a frequent highlight, as is the strong lume. Some owners note the GMT variant offers full GMT functionality, while others point out the movement's date-only nature on certain models leads to a vestigial crown position. The animal artwork on the display caseback is a point of contention, with some finding it detracts from the view of the movement. Overall, owners rate the Boldr Safari highly for its value and distinctive design elements.
