For most hunting-case watches, the lever protrudes from the bezel at 21 minutes for a 16-size watch and 27 minutes for an 18-size watch. Or, if the case has hinges, there should be a raised lip, just clockwise of the pendant, with which to pry the bezel open on its hinge. The bezel may screw off to expose the lever. Typically, for open-face watches, the lever is at 6 minutes for a 16-size watch and 11 minutes for an 18-size watch. On an open-face watch, the lever is located under the bezel (the metal ring that holds the crystal). This was to prevent the inadvertent changing of the time while winding a watch.

Lever-set means that you have to pull out a lever to allow the crown (winding knob) to engage the hands to set them. To meet the post 1906-1908 railroad watch requirements, the watch is lever-set.

The rough movements may sit around in inventory for years before being withdrawn from stock and sent to the finishing room. If sales are slow, the rough movements aren't finished until they're needed.
