Under pressure

Our Ringlock system, introduced in 2008, equips our diving watches designed for extreme depths. It is a unique and patented case structure which can withstand the colossal pressure of the abyss. In turn, let us dive into its distinctive three-layer architecture.

First comes a slightly domed sapphire crystal no thicker than a few millimetres. Deeper, we encounter a highly resistant compression ring made of nitrogen-enriched steel. Then, deeper still is found a RLX titanium case back. In the wake of our original Oyster case, the first milestone in our mastery of waterproofness, the Ringlock system is the expression of a conviction and an ambition constantly reaffirmed. To us, as unforgiving as it is, pressure is a catalyst in our quest for perfect hermeticity, pushing us to take our mastery of waterproofness even further. And if we’ve managed to make it an ally, it is to enable you to reach for new horizons.
