Research Note: Factory records designate this run 4477001-4478000 as Grade 410, Model 5 Openface. However, a batch within the run (4477501-4477800) was actually produced as hunting configuration (Model 6) - most or all with conversion dials that omit the seconds bit so the watch can be fitted in an open face case. The database has been updated according to this insight.
