The watch comes boxed with a diamond authenticity certificate as well as instructions and other printed materials. Also included is a small booklet about the five-year guarantee on the watch with the original receipt contained (showing the watch was bought new for £250)
This watch was originally purchased in September 2010, and so is still well within its original guarantee.
The watch runs from energy stored from light sources, allowing it to run up to 4 months in complete darkness. Normal use of the watch, however, will keep the battery charged from natural and artificial light alike, allowing you to never need to buy another battery.
