Other Details


NOTES:  This watch has been tentatively identified as the Lido based on G-S Crystal Catalog No. 43, which lists this crystal as belonging only to that model. 


UPDATE:  I now have a second example of this watch (also shown below).  The second example is dated 1936 (by movement and case) and runs on a 6AE, 17-jewel movement.  The case on the second example is signed inside and out.
