In October 1998, Nokia overtook Motorola to become the best-selling mobile phone brand, and in December manufactured its 100 millionth mobile phone. A major reason why Nokia grew against its main competitors Motorola and Ericsson was that it managed to cater to the consumer youth market and fashion-oriented consumers, most significantly with the Nokia 5110 and 3210 handsets which featured a large range of colourful and replaceable back-covers called Xpress-on. One of the earliest fashion phones in 1992, from Swiss watchmaker Swatch, was based on Nokia's 101 handset. The company would also form the Vertu division, creating luxury mobile handsets.
