Matte ceramic around a recessed face
The subdued black bezel absorbs glare around the RM 055's open display. Fasteners remain distinct against that surface, and the black strap carries the low-color treatment onto the wrist. The face consequently reads deeper than it would inside a brighter perimeter.
APSF uses a custom-modified manual movement with dark treated bridgework in an RMUL2-style skeleton layout. Those recessed forms give the watch its close-up interest; the matte ceramic case keeps them visible without adding gloss or a large color accent.
