Hi Magnus,
thanks for sharing!
That?s in fact a very rare one.
And the description is very very interesting, especially the dates of production and sale. Quite unusual, even among the Peseux 260.
Do you have some more informations about this movement or watch?
Especially where it was tested and if the pictured P260 is a Breguet watch?
Thank you a lot!
Greetings from germany,
Peter
