I have Hamilton mantel, 2 jewels, 150-010, clock I just received from mother. No date on clock. Has the number 80 just above the Hamilton. Made West Germany. Can't read section that advises adjusted or unadjusted. This part is to small. Need key to wind. Has 2 holes for winding on front panel. Please advise where to attain key and possibly year of manufacturing if can determine from this information.

80 means it was made in 1980. After, I believe 1985 letters started being used instead of years.

the 80 will be on the top of all the other words
should be something like this
80 year of clock
name of clock like "hermle devision"
how many jewels tow (2) jewels
mand in germany

any clock place can sell you a key.
