ANTIQUE LADIE'S WRIST WATCH

MY GRANDMOTHER LEFT THIS WATCH TO ME, WHEN I TURNED 18 YEARS OLD IT WAS GIVEN TO ME. I'VE HAD IT IN MY POSSITION FOR ALMOST 38 YEARS. THE WATCH BAND MEASURES 4 INCHES. THE CLASP ON THE BAND SAYS 1120- 12K GOLD FILLED.
PAT. 2097.055 U.S.A.
ON THE ENDS OF THE BAND THERE ARE O RINGS
PAT.2.266.951
ON THE INSIDE TOP CASE NUMBER 783
ON THE INSIDE BACK CASE NUMBER2783
THE CASING HAS NO IDENTIFING NUMBER.IT DOES HAVE THE WORDS.. CRYSLER WATCH COMPANY, SEVENTEEN, 17 JEWELS
SWISS, UNADJUSTED, YXD
THERE ARE 2 DIAMONDS SET IN A SILVER TRIANGLE THAT CONNECTS THE WATCH TO THE BAND.
THE NAME CRYSLER ALSO APPEARS ON THE DIAL.I TRIED TO SHOW THE THICKNESS OF THE CRYSTAL, BUT I IS NOT VERY CLEAR.
THE 2 NUMBERS 783 AND 2783 THAT ARE ON THE INSIDE OF THE CASES HAVE BEEN IMPOSSIBLE FOR ME TO IDENTIFY.I WOULD LIKE TO KNOW WHAT THE NUMBERS MEAN,AND IF ANYONE HAS EVERSEEN OR HEARD OF THIS WATCH COMPANY. I'VE TAKEN IT TO SEVERAL ANTIQUE DEALERS BUT THEY HAD NEVER SEEN THE CRYSLER WATCH COMPANY BEFORE. IT ALSO RUNS LIKE IT WAS NEW.
