Ball Engineer Hydrocarbon DeepQUEST Protector Watch DM3002A-S10C-GR
The Engineer Hydrocarbon Deep Diver represents the ultimate expression of professional dive watch engineering. Built for extreme underwater exploration, this timepiece combines Swiss precision with uncompromising durability. At its core lies an automatic BALL caliber RR1101-C movement, COSC chronometer certified for exceptional accuracy. The watch delivers an impressive 1000m water resistance—capable of withstanding the demands of technical diving and deep-water expeditions. A patented helium release valve crown allows safe decompression during saturation diving operations. Engineered for visibility in darkness, 15 micro gas tubes illuminate the hour, minute, and second hands plus the dial, ensuring readability at any depth. The green dial provides striking contrast and professional aesthetics while maintaining legibility in challenging conditions. Built from a titanium single block case, this 42mm instrument weighs approximately 210g—significantly lighter than steel alternatives without sacrificing strength. The case height of 15.5mm ensures a balanced profile, while the 3.9mm anti-reflective sapphire crystal maximizes clarity. A unidirectional rotating bezel with Super LumiNova enables precise dive timing in low-light environments. Shock resistance rated at 7,500Gs and anti-magnetic properties at 4,800A/m protect the movement from impacts and electromagnetic interference. The tapered titanium and stainless steel bracelet features a patented folding buckle with extension system for secure wear over wetsuits. A screwed-in crown provides additional water-sealing reliability. With a 53mm lug-to-lug distance and 21mm lug width, this professional-grade diver accommodates diverse wrist sizes and strap options. A watch engineered for those who venture where few dare to go.
