This approach makes good sense. The arrows on the new watches allowed the factory, dealer and customer to see that the chronograph had the improved movement, without opening the case to look for the "I" below the balance wheeel. And we would imagine that the service department would not stamp these marks on a case, as the customer might be upset that his perfect case had been marked.

Sorry for any misinformation . . . Chronomatics page will be corrected soon.

Also, there is no good explanation / legitimate reason for a case with the arrows to have a Caliber 12 movement, other than the explanation that the Caliber 11-I movement had been replaced with a Caliber 12 movement, at some point in its life. Again, we could expect this to happen, as the Caliber 12 was an improved movement from the Caliber 11-I.
