Baume & Mercier Chronograph 1950's 1919 Chronograph

Baume & Mercier 1950's 1919 Triple Calendar & Moonphase. Condition is Pre-owned. This watch was worn sparingly and I am unsure of the maintenance history. The functions on the watch do work and it appears on the lugs there is some marks/ scratches from whomever put on the band. This is noted in the pictures. I do not have a box or papers with this watch. If you would like any additional pictures or have questions please let me know! Thank you for looking and if you would like to have insurance please let me know and I can add this.
