Author POV

Adding a chronograph to a dive-watch case changes the proportions problem entirely — you're now fitting pushers and subdials onto a bezel-heavy 45.5mm face, and caliber 9900 handles it by keeping the layout legible rather than cramped, which is the detail I actually score. The grey dial on rubber is the right call here; a busier dial would fight the chronograph registers for attention. 600m is plenty for a piece that's realistically going to spend its life being timed at a desk, not a dive computer. At ~€9,900 you're paying for the complication and the manufacture movement, and on those two axes it earns the price.
