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.

Baltic Prismic

The Baltic Prismic is widely praised for its unique stone dials, slim 9.2mm case, and retro-chic design, with reviewers highlighting its impressive build quality and detailed finishing for the price. Owners appreciate the complex five-part case construction using steel and titanium, and the attractive dial textures. The hand-wound ETA Peseux 7001 movement is consistently mentioned, offering a 42-hour power reserve. However, some owners find the watch overpriced and the bracelet unappealing or flaring on smaller wrists, while the 30-meter water resistance is noted as delicate. The avant-garde dial design is also described as divisive by one reviewer. Overall, owners and reviewers rate the Baltic Prismic highly for its distinctive stone dials and slim, vintage-inspired case at an accessible price point.

From video reviewers

The Baltic Prismic's unique natural stone dials, each using a slice of thousand-year-old stone, are a standout feature. A notable drawback is the price, with several reviewers mentioning it as a potential issue, particularly considering the finishing and uniqueness offered. Reviewers disagree on the watch's ruggedness, with some viewing it as a dress watch and others not mentioning this aspect.
