Look closely at an atom and you find a core surrounded by constant motion. The Tsar Bomba Atomic builds its dial on the same idea, stripping away the surface so the movement sits at the centre of everything you see. Circling it, each function keeps its own orbit, with a power-reserve gauge at 12 o'clock, the month at 3, an AM/PM indicator at 6 and the weekday at 9, plus a date window alongside. In White, a crisp white shell and matching strap set off the black skeleton.

Driving it all is a Japanese Miyota 9100 automatic, with 26 jewels, 28,800 vibrations per hour and around 40 hours of running time. The 45mm case and bezel are cut from solid ceramic beneath a sapphire crystal, water resistant to 50 meters (5 ATM), and the fluoroelastomer band swaps out in seconds without tools. It shows you exactly what a mechanical watch is made of.
