[Illustration: Figure 15.--VERGE AND LEVER for an Auburndale timer. The one on the left beats eighths of a second; that on the right beats quarters. (In author's collection.)] Five jewels are found in most instances, two cap jewels and two hole jewels for the balance staff and a jeweled impulse pin. One of the faults of the movement is that the cap and hole jewels on the balance are not separable for cleaning. After the jewels were inserted part of the setting was spun down over them, making the assembly permanent. A few movements with only one jewel are known, the cap and hole jewels being metal "jewels" likewise set under a spun-over rim. Whether or not the impulse jewel found in these last-mentioned movements is original or a later intrusion remains undetermined. It is easy to conceive that the factory would see no more necessity for an impulse jewel than for other jewels. The lever escapement is the only one known to have been used, but two varieties of this are found (see fig. 11). One is a standard club-tooth lever with banking pins, the other, much more interesting because unconventional, has pointed pallets and all the lift on the escape wheel, which has very short stubby teeth, very much like the wheel of a pin-pallet escapement. No banking pins are used, the banking taking place between the pallets and the wheel. An examination of a number of these watches, with serial numbers ranging from 46 to 507,[31] reveals no correlation between the serial number and the style of escapement, from which one may conclude that the pointed pallet escapement was originally used; later four balance jewels were added and the escapement changed to the conventional club-tooth pattern. As complaints came in about the defective running of the watch these changes were apparently substituted at the factory in customers' watches. The movements with the pointed-pallet escapement seldom show much wear; on the other hand, watch no. 224,[32] which has the conventional escapement and five jewels, is very much worn and must have run for many years. These watches are stem wound by turning opposite to the usual direction and are set through the winding crown after actuating a setting lever located under the front bezel. The plates, bridges, and ring gear are nickel-plated and highly buffed, making a very showy movement, the only instances of such a finish on watches in the author's experience. In figure 12 is shown a 24-hour dial to fit the movement. Special dial gearing would be required for the hour hand to accompany this dial.
