It took me about 8 years to figure it out with a watch that I couldn't use for chrono purposes, and an AD even quoted a full service to correct it before a kind watchmaker took care of it in about 30 seconds and explained to me how.
This kind of secret information is known only to watchmakers...an those that RTFM that came with the watch. 馃槈
Tis' the trouble though, the watch was only 5 years younger than I am, so box and papers were long gone as they are for many old watches, I genuinely thought and then had that reinforced by a sales guy at the AD (when I was only about 17/18) that the watch needed a $1100 full overhaul to correct it. These days I know the average AD salesman knows little other than the price and brand name on most pieces they stock.
You do know that you can zero the subdials yourself, from memory on that TAG chrono caliber you pull the crown out to second or third position, and push the chrono start and reset pushers over and over to bump the subdial hands back where they need to be.
