Serica Ref. 6190 Field ChronometervsMaen Grand Tonneau Ultra Thin

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.

Owners widely report the Maen Grand Tonneau Ultra Thin features a La Joux-Perret D101 manual-wind movement and a double-layer enamel dial. Some owners criticize the bracelet design and find the dial too small and lacking indices. One owner describes the Maen Grand Tonneau Ultra Thin as "hideous with a good movement." On balance, owners are divided on the Maen Grand Tonneau Ultra Thin, with some appreciating its movement and dial while others find its design unappealing.
