The Artifact

Two materials,
a single light.

The 126603 combines Oystersteel and 18 ct yellow gold. The DLC goes onto the steel only: outer links, shoulders, caseback. The gold remains bare — bezel, crown, centre links. The result is not a two-tone watch: it is gold suspended in the dark.

The Bracelet

Centre links,
in gold.

On the Oyster bracelet the centre links are solid yellow gold: they remain untouched and polished, while the outer links go to DLC. The treatment is masked piece by piece, by hand, before deposition — there is no faster way to do it.
