Blue ceramic compression ring
Withstanding extreme pressure
The compression ring is made from blue ceramic, a technical innovation that marks a new way of integrating this material into the watch case. This Cerachrom ring, which is decorated with a circular satin finish, forms part of the Ringlock system, a case architecture that enables the watch to withstand the colossal pressure of the abyss at depths of up to 3,900 metres (12,800 feet). The uniformity of colour between the dial, bezel insert and compression ring is a triumph, accentuated by the 18 ct yellow gold of the case and the Oyster bracelet.
