A discontinued or vintage timepiece that has never been sold to a retail consumer, never worn, and preserved in its original factory condition, often retaining protective factory stickers.

A unique alphanumeric identifier engraved on the watch case, movement, or rehaut by the manufacturer. No two authentic watches produced by a brand share the same serial number.
