What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Seestern Sub 300 V4

Owners widely praise the Seestern Sub 300 V4 for its terrific fit and finish and surprising little touches at its $179 price, noting top-notch case, dial, bezel, and crystal. The bracelet is considered nice enough for the price point, and the watch is powered by the solid and reliable Seiko NH35 movement. Some owners report that the polished sides of the case show signs of wear. Overall, owners rate the Seestern Sub 300 V4 highly for its excellent case, dial, and bezel finishing at the price.

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.
