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.

Sternglas Naos Automatik

The Sternglas Naos Automatik is praised for its stylish Bauhaus design and solid build quality for its price, featuring a sapphire crystal and elegant case. However, some dial text is too small and slim for easy readability, and the Milanese strap and clasp are considered lower quality, with the quick-change system also not meeting the brand's advertised standard. One owner found the 38mm model lighter than expected and preferred it over a Seiko SRP703 and an Apple Watch. Overall, owners and reviewers highlight the Sternglas Naos Automatik's attractive Bauhaus design and good value, despite some criticisms of dial legibility and strap quality.
