The watch was originally developed to accompany speleologists on their cave exploration expeditions and as such was designed with extreme durability in mind. Due to its limited commercial success and short production period, the reference 1655 is today one of the more sought after Vintage Rolex models. The model features a fixed bezel with 24 hour display and a special 24 hour hand that can be set to distinguish day from night hours. It is known as the 'Freccione', Italian for 'big arrow', amongst collectors. For further information on this lot please visit Bonhams.com
