Serica Ref. 6190 Field ChronometervsZelos Mako 4

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 praise Zelos' dial finishing, with specific admiration for blued markers and hands, and the unique titanium bezel insert. Reviewers highlight the Mako 4's impressive case finishing and fully lumed ceramic bezel for its price point, noting the boxed sapphire crystal and wavy dial texture contribute to a vintage feel. The Sellita SW200 movement is described as reliable, with one owner reporting accuracy of -0.3 seconds per day. However, the crown can be difficult to grip, and the winding mechanism offers resistance when screwing down, while the watch's height may hinder wearability under a suit cuff. The tropic rubber strap is considered excellent, in contrast to a stiff leather option. On balance, owners and reviewers rate the Zelos Mako 4 highly for its exceptional dial and case finishing at its price point.
