Silverknapper,
The Aerospace basically consists of a case and a sealed module inside. The sealed module is used in Tisssot watches. You pay for the Titanium Breitling case.
Breitling don't make their own movements, you see.
Mine (before I got rid sharpish) had a minute hand that wasn't the most stable. A common problem on the aerospace model, which is a shame as functionally it wasn't bad.
Stoppers, send it off to any decent watchmaker who will put it right for you. Then flog it!
