REACHING NEW DEPTHS

The Ultra Deep made history when it reached the deepest place on Earth during the Five Deeps Exhibition in 2019.

Adapted from that record breaking model, this unique collection has been tested in real ocean conditions, is water resistant to an impressive 600 bar, and comes with an extra diver extension for the strap. Meeting the ISO 6425:2018 standard for saturation divers’ watches, this remarkable timepiece can perform at new depths.

UNRIVALLED PRECISION

This 45.5mm watch is presented in an O-MEGASTEEL case, with a bracelet also crafted from O-MEGASTEEL – a new, high performance stainless steel alloy offers greater polish and shine, as well as superior strength.

The lacquered dial transitions effortlessly from blue to black, while 18K white gold and white Super-LumiNova hands and hour markers enable enhanced visibility.

The 8912 calibre movement provides unrivalled precision in any conditions.
