QC should focus on the black embossed dial, bezel surface transitions, strap attachment, rubber finish, and fold-over clasp engagement. A clean review confirms that the exact black-and-black configuration remains distinct from the blue-strap 5167A-001 before dispatch.
Review the wrist image last: it shows whether the black dial and black strap keep the Aquanaut visually compact when worn. That is the practical distinction from the 5167A-001, whose blue strap intentionally introduces a second color. If the aim is one controlled line from dial to strap, the 5167A is the clearer selection.
The black 5167A is easiest to assess as a continuous line from dial to strap. Check that the embossed dial remains readable under the same light in which the tropical composite rubber appears black, then use the angled case view to make sure the polished chamfers do not interrupt that restraint. Against the blue-strap 5167A-001, this version wins when a second color would make the watch less useful across the intended rotation.
