The Chronofy Watch Guide app for iPhone and iPad

Until now, deciding on a fair, competitive price to pay for a pre-owned watch was based on guesswork, unverifiable web searches and hard to understand publications.

Our guide takes the guesswork out of luxury watch trading and helps avoid costly mistakes by employees who may have limited watch trade knowledge or experience.

The Chronofy Watch Guide combines the knowledge and experience of multiple watch experts in an easy-to-use publication complete with color photographs, reference numbers and descriptions of hundreds of luxury watches. The guide provides suggested current values for each watch based on its condition --- “Retail”, “Mint”, “Average” or “Rough”.
