1930s omega tank

[zerozero2]

Hi guys! I just purchased what seems to be a 1930s omega tank watch and am now struggling to confirm its authenticity. Tried looking online for anything that could help me identify it accurately but was left more confused by all the information I found. It would be great if you guys could help me authenticate and/or identify this piece.

Looks nice. What did you want to know? If you show the movement, we could certainly identify the calendar. I think it has been determined that the KB is the maker's mark for Kessi Freres.

However this story ends, that’s a nice looking watch

Nice original piece. IMO with a cal T17 inside
