The Portugieser with a flyback chronograph, and an unusual way of reading one. Elapsed hours and minutes share a single subdial at twelve, their hands stacked concentrically, so a timed interval is read the way you read the time itself instead of being assembled from two separate counters.
- The combined hour-and-minute chronograph subdial at twelve is specific to calibre 89361.

How do I check a IWC Schaffhausen IW3905 with Watch Safe?
Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
