You're assuming that steel is inferior and plastic is superior. My 45 year old steel bike still functions as it was intended - it is still transforming energy into forward motion. ...and by 'less accurate' I'm assuming that you meant 'less efficiently' The actual mechanics of a bicycle have not changed. A bike still utilizes a large cog, transferring the input energy to a smaller cog by use of a chain... The only thing that has changed (in watch parlance) is the case.
