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 ExP-02

Oak & Oscar The Humboldt ExP-02 is a 39.5mm stainless steel tool watch featuring a unique, layered aluminum "ghost dial" for legibility and 200m water resistance, powered by a Sellita SW300 movement. Its appeal is limited by a US$2,550 price and an extremely limited production of 20 pieces, with its experimental dial construction done in Chicago. Overall, reviewers highlight the endearing dial and in-house bezel production as key features of the Oak & Oscar Humboldt ExP-02.

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.
