注脚
The company Aluminium Limited specially commissioned Vacheron & Constantin to make a watch predominantly out of aluminium. The case and the plates were all made from the very light metal and produce an exceptionally light but sturdy watch. The watches were given as mementos for employees of the company that attained 25 years of service and were inscribed with a presentation inscription. It is rare for watches to be made of exotic materials especially in series making this a very unusual piece.
