The costliness of Rolex and Prada watches originates from completely opposing sources. The Rolex watches are costly since the company uses material such as fine gold and silver and sometimes fetches a premium in the resale market depending upon the model, it ensures great longevity, makes their own movements, has stringent quality assurance and creates an aura of exclusivity that enables its products to retain or appreciate in value over the years. Prada, meanwhile, stopped actively producing its own watches since approximately early 2012; most Prada watches currently on offer are, therefore, considered vintage. Discontinuation of production inevitably leads to the shortage of supplies, hence the increased prices for the watches. This is especially true of discontinued products that become more exclusive since fewer copies of those exist. As such, many consumers nowadays turn to pre-loved watch curators like Confidential Couture that provide a wide selection of authentic Rolex watches along with discontinued Prada models that cannot be readily purchased elsewhere.
