I just purchased the afore mentioned timepiece, and I noticed only one postion on the winding crown. Is there a safe method to "quick-setting" the date on the manual-wind movement? I know there are some automatics that can be back-wound from 2 or 3 a.m. to accomplish this. But I didn't want to try it without first getting some advice from those of you with more hands-on experience. Photos to follow.
