This 4006-6070 from 1975 is, based upon my observations for the past 6 years, quite rare. Only a very few Bell-matics were offered without the jewel count on the dial and the -6070 is one of them. With a beautiful gold dial, its hands, markers, and day and date wheels are in excellent condition. A small amount of wear on the lugs and the presence of a modern bracelet is why I rate this at 90% (modern bracelet seen in fourth photo; however, I will include the original bracelet as well, but it was too short for my wrist). Timekeeping and reserve are good and I will gladly test for interested parties. Price is $200.00 shipped in the U.S.
