Too many issues on it for me to consider:

- the seller picks up on the non-original crown
- day and month dials are usually white on a 12 Dato, even if the dial is black
- the inner bezel scale doesn't have the seconds scale as well as the days - maybe part of the redial the seller mentions, or perhaps it was a bezel from an earlier Heuer triple calendar that only had the day scale
- corroded date hand with no colour on the crescent

On the other hand, the case and movement looked fine. Cheap price in the end, but how many 12 Dato parts are knocking around to get it up to scratch? Too much of a project in my opinion, plus there are sound watches out there.
