This watch is very rare in this condition as its new old stock. During the 1980s Tissot brought out a number of watches made from a wide variety of different materials, and this Rock Watch is one of them. Minimalist design at its best and something well, a little different! Its quartz movement keeps perfect time as you would expect from a Swiss watch. The granite case measures 30mm in diameter and 34mm from lug to lug, suitable for a lady. The dial is also made from granite with a speckled look that will be unique to this watch, its clean with the logo in the centre, and some funky red and yellow hour and minute hands, all under the mineral crystal. The steel crown is unmarked, the case back features the logo and screws in. Model/serial number R150 #909-7. It comes with the original strap in leather and measures approximately 7.5” or 19cm. The watch comes with the original box but no papers. It has not been pressure sealed, so water resistance is not guaranteed.
