About TSAR BOMBA

Named after the most powerful device ever tested, TSAR BOMBA fuses atomic engineering with the artistry of horology — bold, oversized designs sold in more than 186 countries. Its signature is a patented quick-release system that swaps bezels, straps and crowns in about 30 seconds, across collections like the Elemental, the French Design Award–winning Reactor, Dark Matter, Electron and the transparent Light Matter. Sapphire crystals and Seiko, Miyota and Ronda movements throughout.
