At this time, under the oversight of Jean-Jacques Cartier, Cartier created some of the most interesting and now sought after designs of the vintage watch world such as the Maxi Oval and the Crash. Each watch was hand crafted in the jewellery workshops before being handed to the watchmakers to make up into the finished piece. Each piece would then take approximately a week to produce ensuring their quality and by default their scarcity. During this period Cartier London designed the watch that bears the nickname of the 'Pebble' or in the United States the 'Baseball'. Using the simple juxtaposition of a square within a circle sums up the clear design definitions that create distinctive and original watch designs. By softening the square with rounded edges and flipping the point to twelve o'clock makes it distinctively Cartier. There are estimated 6 large size 'Pebbles' in existence with five in yellow gold and one in white gold with a black dial. Only one other is known to exist with the 'Turtle' lugs which is in the Cartier collection making this probably the only chance to acquire this particular design. It is worth mentioning the diminutive lugs on the overtly round form is echoed in the Ballon Bleu case design showing the DNA of Jean-Jacques Cartier and his influence in the last oeuvre from Cartier.
