Methinks you're right, afire. Seems we've seen grouping of assigned numbers earlier (Favre, Frey, FHF, Aegler) and later (like 675-678 all Peseux variants). Would love to know if any have theories on how these were assigned, or even if there is a pattern of number of calibers in a "block" for each manufacturer.

edit: there's also the question of ebauche maker vs. supplier to Gruen. The Gruen caliber 673 matches FHF caliber 59--but Record was also working with these ebauches. Possibly their caliber 70? (see auction item 153957721244) It's a decade later than the 650, but just illustrating the point.


My two caveats:
1) I'm wrong many times a day --just ask my wife!
2) Always seeking to learn more
