Bulova Tempus Fugit Shelf/ Desk/Mantel Quartz Clock w/ Silent Sweeping Hand---This is one of the prototypes of modern clocks. Bulova, one of the premier clock and watchmakers of the 20th century. They were quite expensive and are still most collectible. Today we have watches which run on rechargeable batteries and disposable batteries the size of grapefruit seeds.The Tempus Fugit ran on C cell batteries. These clocks are quiet companions. This one has been hard tested for 45 days at listing and has worked perfectly.
