Following 316L steel and K gold, titanium has emerged as a premium material in watchmaking. Titanium, a metal resembling steel with a silver-gray sheen, maintains its color permanently at room temperature without blackening. Renowned for its high strength-to-weight ratio, exceptional corrosion resistance, and biocompatibility (nickel-free, hypoallergenic), titanium is extensively used in aerospace and deep-sea diving applications. With a density roughly half that of steel (approximately 4.5 g/cm³ vs. 8.0 g/cm³ for steel), a titanium watch weighs significantly less than its stainless steel counterpart. Its ability to retain strength at high temperatures (around 538°C / 1000°F) further adds to its credentials. These properties – notably its corrosion resistance and lightweight nature – make titanium an exceptionally suitable material for dive watches.
