Serica Ref. 6190 Field ChronometervsOak & Oscar The Humboldt ExP-02

Owners widely praise the Serica Ref. 6190 Field Chronometer for its refined dials and slimmer case, with one owner calling the black dial the "blackest of blacks" and another finding it not top-heavy. The COSC-certified automatic movement is noted, and the Bonklip bracelet is described by one owner as the most comfortable they have ever experienced. However, one owner found the 9 o'clock crown undesirable and noted a ding on the bezel, while another owner found the Bonklip bracelet too small for their wrist. The €990 price is a significant increase from its predecessor, and some may miss the charm of a manual-winding caliber. On balance, owners and reviewers appreciate the Serica Ref. 6190 Field Chronometer for its updated design and comfortable bracelet, despite some concerns about the crown placement and price.

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.
