I. Movement
Every Archive 24 timepiece runs on a Swiss-made quartz movement from a fifth-generation movement-maker based in Lausanne since 1946. They supply brands like TAG Heuer, Tissot, and a long list of houses who prefer Swiss precision.
II. The case
316L stainless steel, the same grade used in surgical implants and fine jewelry.
It resists sweat, salt, and chlorine, wears without scratching easily, and won't react with your skin. The kind of steel you choose when you expect something to be worn often, and kept a long time.
III. Crystal
The crystal is the clear panel over the face, the part you look through to read the time.
Ours is sapphire, second only to diamond in hardness, so it resists the scratches of everyday life and stays clear for years.
IV. Water resistance
Rated to 3 ATM, which means it's safe from the everyday: a splash, a caught-in-the-rain, a quick handwash.
It isn't made for swimming or the shower.
So keep it for your days, not your baths, and it'll keep well for years.
