This unknown caliber is a 15 jewel, 10.5 ligne movement. Not a lot is known about these movements and even more of a mystery is the factory "T" marking.

Bazzab started an identification thread on the vintage forums awhile back. A Gruen dissecting team was formed, Bazzab and I dissected both of our movements.

The only conclusion is the movement is a Fabrique d'Horlogerie de Fontainemelon make.

It is potentially a cal 266 which is a 10.5''' size movement. Setting bridge/works are a close match: link

Agree. I changed the subject line.

Yes, same setting as caliber 610, both are based on the same FHF base ebauche design which Ranfft calls FHF 1144 10.5'''.
The new bridge layout was radically changing the look so it was newly protected in November 1923.
