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 had to be replaced and now keeps perfect time. The mother of pearl case measures 30mm in diameter and 34mm from lug to lug, and has a gold underlay. The dial is also made from mother of pearl with a textured look that will be unique to this watch, it’s clean with the logo in the centre, and gold hour and minute hands have been replaced due to the movement having to be replaced, all under the mineral crystal. The gold crown was replaced along with the movement and hands as one set, the steel case back features the logo and screws in. Model/serial number R150 #957-7. It comes with the original strap in leather/plastic and measures approximately 7.5” or 19cm. The watch comes without the original box or papers. It has not been pressure sealed, so water resistance is not guaranteed.
