Oak & Oscar The Humboldt ExP-02vsSeiko Presage Classic Series “Craftsmanship” Enamel Dial

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.

Owners and reviewers widely praise the Seiko Presage Classic Series “Craftsmanship” Enamel Dial for its high-quality, handcrafted enamel dials, with specific commendations for the depth and subtle gloss of urushi lacquer and the excellent legibility of minimalistic markers and contrasting hands. The watches are frequently cited as offering significant value, with one reviewer noting the SPB163 as a great value at €1,300, and another highlighting the series' impressive 100M water resistance and Japanese design inspiration at $1,300 USD. However, the 12.4mm to 12.8mm thickness is noted by multiple sources as a potential area for improvement, with a preference for under 12mm, and one owner dislikes the date window. Accuracy figures for the 6R27 movement range from -15 to +25 seconds per day, and its power reserve is closer to 35-40 hours than the advertised 45 hours.
