Vintage Waltham Premier 8 Days 1926 7 Jewels Size 37 Car Travel Clock.  My Grandfather had several car clocks and he has passed.  I don't know what exactly these are.  I found another ebay listing with this exact picture, so I copied the header.  I do not know the serial number or how to open the back to find out.  I do not know if it is a 1926 or what 7 jewel even means. But I think these are super cool and that someone in the know can add this to their collection and have fun with it. Bezel glass is perfect.  Brass case is very good.  Some high tarnish on the rear. Stem is strong. Clock is not working and I have no idea how to make it run.  Sale is for parts only. Thanks for looking and please check out my other auctions.
