Grail Watch
Collector slang for a highly desired watch that represents a major personal collecting goal.

Definition
Collector slang for a highly desired watch that represents a major personal collecting goal. The idea is personal rather than a formal market category: one collector's grail may be rare and expensive, while another's may be attainable but emotionally significant. The term usually implies a long-term target rather than simply the next purchase.
Why it matters
Grail Watch is community vocabulary rather than a controlled horological standard. Clear context prevents casual collector language being mistaken for an official specification.
