Hey What size is the movement ? Looks a heck of alot like a 21.29SC pocket , box deck chronometre.... i have sen them in 17j with 3 adj and 21 jewels marked with 5 adj... over the years... Whats the story ? Best bill
Hi Again Took a closer look at your movement... I can make out 2129 but cant see the SC for seconds central... here are some zoom in pics really nice movement... has a lot of age on the plates ! Good Hunting bill
I have also never seen a Longines movement marked 17 Rubis and given the finish of the movement, I would be concerned that it has spent time outside of the case. A message to Longines is in order. Keep us updated!
