I believe these cases were manufactured by
Lascor. However I don't believe you will have much luck getting them to divulge their methods, specifications and processes as this would mean disclosing trade secrets (possible patented). IIRC, I think I read somewhere that the gold inlay is around 2mm thick. In addition to gold in titanium they also did gold in stainless steel and (rarely) a palladium/titanium combination. I own one of the Titane Chronographs
