Montblanc MB M13.21

High confidence

Recorded alongside the M16.29 so the family reads as a family. The catalog does not assert the detailed differences between the Villeret calibers, which are not established here — what is established, and what matters at the point of examination, is that both belong to the Villeret production and neither resembles anything in the Le Locle range.

The Villeret Minerva caliber family and its members

Which calibers does Montblanc currently make at Villeret, how do they differ from each other, and how does each relate to the historical Minerva calibers they descend from?

Scope The catalog holds two Villeret calibers and does not assert the differences between them, which is honest but leaves an examiner able to recognise a Minerva movement without being able to say which one. Given the values involved, being able to confirm that the correct Villeret caliber is present — rather than merely a Villeret caliber — would be worth having.
