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.

Longines HYDROCONQUEST MESH

Owners widely praise the Longines HYDROCONQUEST MESH for its eye-catching dial colors and impressive fit and finish at its price point, with some noting a well-regulated movement losing around 2 seconds per day and others seeing accuracy within COSC specifications. The tapered mesh bracelet is described as a clever execution with emphasized adjustability, offering a neat feature for wrist swelling. However, some owners criticize the bracelet's clasp for lacking on-the-fly micro-adjustments and the potential for pinching, while winding the screw-down crown is considered inconvenient by some. The lume is a point of contention, with one owner finding it disappointing and fading quickly, while another reports it as strong and long-lasting. Overall, owners rate the Longines HYDROCONQUEST MESH highly for its competitive pricing and versatile, modern retro aesthetic.
