Serica Ref. 6190 Field ChronometervsOak & Oscar The Humboldt Seven Year

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 Seven Year owners note the hand-machined brass bezel and hand-finished dial. One owner reports the Sellita SW300 movement timed at -5 seconds per day, and another owner observed minor imperfections on the dial and crystal, along with a small ding on a lug. On balance, owners appreciate the unique dial and bezel finishing, though some minor cosmetic flaws have been noted.
