Where is the serial number on a Mido watch?

Swiss case and movement numbers are usually separate sequences by different makers; only the movement serial, where one exists, is relevant to movement dating.

What do Mido serial numbers mean?

Serials are broadly sequential, but without a published table the practical dating route is calibre plus case reference.

How accurate is dating a Mido watch by serial number?

Limited from public sources: approximate period dating via calibre and style is the realistic route for most pieces.

Where are Mido production records held?

Company records exist within the Swatch Group heritage structure; public serial tables are sparse.
