Your clock is indeed an Auto clock made by Sessions circa 1915. It is called Auto #2 and is an eight-day movement. The pattern was adapted and made for The Ford Motor Company. The movement is heavy brass to be durable in the rough riding cars of that time.
The clock came in either nickel, or black enamel with nickel trim and had a 2 1/2 inch Iveroid dial with second hand.

Thanks Bill, I could not find it anywhere after googling Sessions. Where did you find that info? - link please. What should I do with it? Put it on ebay? what do I ask in price for it? I have inherited many collector's clock from my dad who was a longtime NAWCC member - should I submit a pic here for each clock or should I take group pics and maybe you can identify them?
