Meanwhile, independent German horologists like Sinn Spezialuhren and Damasko source genuine Austenitic Submarine Steel (1.3964 / XM-19) directly from ThyssenKrupp Marine Systems. Engineered for the outer hulls of German Type 212 non-nuclear submarines, this material boasts double the yield strength of conventional luxury steel and complete non-magnetic resistance. By measuring Pitting Resistance Equivalent Numbers (PREN), standard luxury 316L steel scores between 23 and 28, whereas German submarine steel scores roughly 39. Machined in specialized Saxon case facilities like SUG Glashütte, timepieces like the Sinn U1, Sinn U50, Sinn UX, Damasko DS30, and Damasko DSub10 represent a masterclass in functional yield, offering indestructible tactical hardware for a fraction of traditional luxury prices. PEOPLE ALSO ASK: Q: What is German submarine steel made of? A: German submarine steel is a high-grade austenitic alloy designated as 1.3964 (XM-19), enriched with nitrogen, chromium, nickel, and molybdenum for absolute resistance to saltwater pitting. Q: Why is submarine steel better than standard Swiss luxury watch steel? A: Submarine steel features a PREN score of roughly 39 compared to 316L steel's score of 25, offering twice the yield strength, non-magnetic permeability below 1.01, and zero ocean corrosion. Q: Are Sinn and Damasko watches actually made from military submarines? A: Yes, both manufacturers source raw 1.3964 hull steel directly from German naval suppliers like ThyssenKrupp Marine Systems to mill their watch cases.
