Engineering is where Arena’s ideals take physical form. The Vanitas’ dimensions, 39 mm diameter, 12.5 mm thick, and 47.5 mm lug-to-lug weren’t chosen by chance. They were the result of countless design iterations measured against ergonomics, durability, and balance on the wrist.
The fixed-lug construction ensures absolute security under strain; the low-profile case and precise crown geometry protect the movement without compromising wearability. Inside, the SW300-1A is adjusted for reliability, enclosed in a case rated for the demands of both depth and altitude.
Every drawing and test shown here is a record of that pursuit: to engineer a timepiece capable of existing wherever its wearer does, because reliability, like time itself, is earned through repetition and discipline.
