Fit: Incomplete (lug-to-lug unpublished). Casio does not publish lug-to-lug. HiConsumption, Man of Many and WatchDavid (third-party) list 44.7 mm lug-to-lug. That figure is not used for a fit score. Thickness is also unpublished: 11.4–11.6 mm (sources differ).

The flat top of the wrist (usable span) is the width a watch can sit on without its lugs hanging over the edge.

WatchDavid lists three versions for Europe. Whether CMK-100TCC-8A and CMK-100TCL-5A reach Europe has not been announced, WatchDavid says.
Thickness. Montres de Luxe (third-party, 27 October 2026) gives 11.6 mm. HiConsumption, Man of Many and WatchDavid give 11.4 mm. Thickness: 11.4–11.6 mm (sources differ).
Movement name. The press release does not name the calibre. HiConsumption and WatchDavid (third-party) say Module 5766, about 42 hours.
