TOOL INDEX

THE TOOLS

Client-side instruments built on the file's own data. Each one answers honestly, including when the honest answer is a band, a pair of candidates, or a disagreement worth knowing about before you bid.

SEIKO SERIAL DECODER
year and month from the caseback serial, narrowed by reference window
ROLEX SERIAL LOOKUP
numeric and letter-prefix eras in honest year bands; random-era education included
OMEGA SERIAL LOOKUP
the dedicated Speedmaster chart — the one the standard tables get wrong
Production runs end. The file on the reference never does.
