When the seller says "This watch does not appear to be in its original condition"...

and yes, the case also looks dubious.

 

The 15.26 is a pocket watch caliber released in 1911. This particular one is from 1915-ish. Some frankenmaster stuffed it into a more modern wristwatch case and repainted the dial.

 

Sounds like he was taken to the cleaners in 2016!

"Purchased on 7th Avenue in Manhattan in 2016, for approximately AUD $1300."

 

It's a Frankenstein watch!
Case is Generic (not Longines) and Dial is Reprinted, only the caliber is original Longines.
