RALF TECH THE BEAST Electric Black Amphibian 48mm
Built for the point where land ends and another world begins.
THE BEAST Electric Black Amphibian takes RALF TECH's extreme professional diving instrument and gives it an even more uncompromising identity.
Its massive 47.7mm case is manufactured from 316L surgical steel, sandblasted to a matte finish and treated with black PVD. Above it sits the professional Diamond Shape bezel, developed for secure handling underwater and fitted with a scratch-resistant black ceramic insert.
At the centre is the detail that defines this edition.
The matte-black Amphibian dial was created around RALF TECH's collaboration with former US Navy diver Jeff Scott. Its distinctive octopus-and-trident emblem represents the ability to move between two environments — land and water — while acknowledging the marine DNA at the heart of RALF TECH.
And THE BEAST is considerably more than visual theatre.
A 6mm curved sapphire crystal, protected screw-down crown and RALF TECH's exclusive encapsulated caseback contribute to an extraordinary 3,000 metres / 9,900 feet of water resistance.
Inside is the RTE001 Long Range Electric Micro Hybrid movement. Developed in Switzerland for RALF TECH, it reduces the number of moving components while combining quartz precision with extraordinary efficiency. Its autonomy can reach 100,000 hours — almost 12 years.
A black silicone strap is supplied for professional and everyday use, together with a second black Zulu strap.
Only 50 pieces will be produced.
Why buy it?
Because THE BEAST Black Amphibian doesn't merely look capable.
Three thousand metres of water resistance, a 6mm sapphire crystal, encapsulated caseback and almost twelve years of autonomy make this an extraordinary piece of engineering.
But the Amphibian adds something else: identity.
The black PVD case, specialised dial and octopus-and-trident emblem turn an already unusual diving instrument into something genuinely distinctive.
A watch created for two worlds — and considerably over-engineered for both.
