Production Year
A watch specification field known as Production Year, used to describe or compare a measurable or identifying characteristic of a watch.
Also known as: Year of manufacture, Manufacture year, Production date
Definition
Production year is the year in which a watch or major component was manufactured, which may differ from its retail sale date, warranty activation date or model-launch year. Dating methods vary by brand and era: serial ranges, caseback codes, movement numbers, archive extracts or original papers may provide evidence. For watches assembled over long production cycles, individual components can also pre-date final assembly.
Why it matters
Production year can affect specification, originality, rarity and value because manufacturers often make running changes within the same reference.
