Anthony Marquié is a French national and a trained aeronautical engineer who swiftly turned to an international career in finance and investments. He has always been passionately interested in both modern and vintage watches, and soon began collecting several types of emblematic models, including many icons from the OMEGA brand. Grégoire Rossier is a Swiss bioinformatics specialist. Fascinated by watchmaking, he has developed a systematic database comprising thousands of entries referencing all his observations as well as market trends. This database is the foundation of the scientific approach on which this book is based.
