Here one prime example of supplier mistake…
like nearly all watch brands of a certain era, they relied heavily on suppliers for many of their components. While the final quality inspection was up to Patek Philippe, things can always fall through the cracks.

A very easy one.

Easy one,
but easy mistake too: this typo is still current in French language nowadays...
What's the point in doubling letters that one can't ear? most probably a reminder from ancient Greek or Latin.
Thus said, I find it normal that the brands are outsourcing components (each component being a speciality)
but absolutely no excuse for failing in their QC duty.
