Curator Response: Thanks for the report and upload. I can see the movement is an openface, lever-set, 18-size, model 3. The screw-set jewels and a micrometric regulator would classify it as Grade 70. (Keep in mind the configuration, openface vs. hunting, is determined by the movement, not the case).

Grade changed from 55 to 70
