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.

Grand Seiko SLGW003

The Grand Seiko SLGW003 is praised for its comfortable, lightweight Brilliant Hard Titanium case, meticulous finishing, and a clean, modern dial. Reviewers highlight the new 9SA4 manual-wind movement, noting its attractive finishing, 80-hour power reserve, and accuracy of -3/+5 seconds per day. It is considered a versatile dress watch blending vintage and future Grand Seiko spirit. The €11,700 price is noted as expensive, with some questioning its value. Overall, reviewers rate the Grand Seiko SLGW003 highly for its elegant design and impressive manual-wind movement at its flagship price point.
