the difference between two pieces of ref.6694

I saw two Ref. 6694 with different dials.

One of the dial  printed with royal chronometer, and the other one havenot it.

I want to know the difference between these two dials cause of  different manufacturers?

Whether this distinction can be used as a judge of the production time ? maybe the dail with chronometer royal made later than the other one?

All the Ref, 6694s I've seen before have "Royal Chronometer" or "Chronometre Royale" on the dial (nt)

I see there are several 6694s that do not have Royal Chronometer written on them, so it should be possible.

the most important is having Chronometre Royal on the caseback, as you mentioned there
