Confusingly, no.
TC are not Tiger Concepts.
TC was a watch sold by a person whose initials were TC, and he had the unique position of saying that people who got a watch from him weren't customers, they were like-minded watch fans, that he was really only pursuing figuring out how to build the very best watch that he could, which is why people liked them and they continue to appreciate in value. They're harder to find now that he's stopped doing it.
