The Ringlock system, introduced in 2008, equips our diving watches designed for extreme depths. Its unique, patented three-layer case structure – slightly domed sapphire crystal, highly resistant compression ring made of nitrogen-enriched steel and RLX titanium alloy case back – can withstand the colossal pressure of the abyss. The Ringlock system serves as a catalyst in our quest for perfect hermeticity, pushing our mastery of waterproofness even further.
