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.

Seiko Baby Alpinist

Seiko Prospex Land owners widely praise its comfortable, sub-12mm cushion case that wears smaller than its dimensions suggest, and its sharp, attractive appearance featuring outstanding brushing and applied indices. Reviewers note its legible dial, solid movement, and 100m water resistance at a fair price, with some owners appreciating its unique combination of features. However, the stock strap is consistently described as stiff and uncomfortable, and one owner would prefer a numbered bezel over cardinal directions. Accuracy is reported around -10 seconds per day, and the internal rotating bezel's action is considered good for the price but not as refined as higher-end models. On balance, owners and reviewers rate the Seiko Prospex Land highly for its comfortable wearability and attractive finishing at its price point.

From video reviewers

The watch's bezel action is smooth and precise. The watch's lume is somewhat lacking, with the hour markers not being as bright as they'd like. Reviewers disagree on the ideal case size, with some preferring 38mm and others 41.4mm.
