Most major watchmakers utilize high-grade, off-the-shelf alloys like 316L or 904L stainless steel, mass-produced via CNC machining and hydraulic stamping to ensure uniform quality and corrosion resistance. These methods are efficient but they prioritize industrial efficiency.
Sopwith’s process, however, involves:
Thermal Enhancement: Melting reclaimed historical steel and comparing its composition to modern aerospace benchmarks like AMS grade 5360.
Hardening & Coating: Upgrading 20th century wartime steel to modern standards to ensure it is corrosion-free and wearable for a lifetime, often applying titanium carbide coating to enhance scratch resistance and durability.
By owning the entire metallurgical pipeline, Sopwith transforms brittle wartime artifacts into robust, luxury-grade timepieces that Oracle of Time describes as "living artifacts". This creates a product where the history is not just a feature, but the very foundation of the watch.
