Carbon and DLC steel continue the case language into the bracelet. That matters because a plain metal bracelet would break the custom look at the lugs; this one keeps the dark geometry moving around the wrist.
Blue in the center changes how the black forged-carbon case reads: instead of a nearly monochrome object, the watch has an immediate point of focus. The carbon marbling remains visible around the dial and along the composite bracelet, so the custom treatment is still integral to the design. Celeste is the quieter Black Grail sibling, keeping attention on black texture and small accents. G-Blue suits a collection that already has a conventional steel Nautilus and wants the familiar outline in a much more graphic form. The bracelet continues that black frame at the wrist.
Before dispatch, our QC team reviews blue-gradient consistency, carbon-surface finish, case-to-bracelet alignment and clasp closure.
