Dial:
The dial is in excellent, original condition. There is no wear to writing. There are no areas of damage to the enamel. This is a very good dial for the age.
 
Hands:
Excellent condition Cathedral hands with no rust. Thermally blued.
 
Glass:
The crystal is in good condition with only some very light surface scratches.
 
Crown:
The crown is likely a replacement as the colour doesn't match. In good condition, with some surface scratches.
 
Case:
The case is in excellent condition with only light surface scratches that are consistent with age. This remains original and un-polished.
 
Case back:
Strong condition with multiple light surface scratches. Nice coin edge back.
NOTE: The thread on the screw back needs to be on correctly and carefully to tighten equally all over.
 
Lugs:
The lugs are thin silver and are deformed due to age. This can be corrected. It doesn't notice with a strap on.
 
Movement:
Keeping time to within -120 seconds a day with an amplitude of 200 degrees. The beat error is 9.9m/s.
It keeps good time during wear and sat on a desk but ideally needs a service.
