When used intensively, a watch is liable to two risks : scratching and breaking. As diving instruments built for adversity, the new Panerai Submersible watches are highly exposed. The brand has therefore created an extremely resistant model, the Submersible BMG Tech PAM799. The area most exposed to scratching is the upper side of the watch, composed of the glass and the bezel. For the former, the solution is standard, a transparent synthetic sapphire crystal, while the latter is made from a composite based on carbon fibers and an ultra-hard solvent named PEEK. Carbotech creates a mottled appearance and ensures exceptional hardness. As far as breakage is concerned, the issue is more complex. Materials resistant to rupturing, such as steel or titanium, tend to scratch easily, while scratch-resistant ones, such as ceramic, are liable to break. To optimally combine the two, the PAM799 uses BMG-Tech. It looks like a steel, yet this complex alloy is a metallic glass. It has the strength of metal, and the amorphous crystal structure of glass, meaning so irregular that it prevents shocks from spreading and becoming a fracture. The BMG-Tech Submersible can therefore withstand just about anything.
