In 2005, two limited editions of the 1972 model were released for the brand's partners and employees, commemorating its 250th anniversary. One of these limited editions features a pink gold rectangular asymmetrical case with a quartz movement. The dial is in dark anthracite grey with painted white Roman numerals and the anniversary dates '1755' and '2005' at 12 o'clock. The caseback is engraved with the date '17 September 2005 250'.
In the 1970s, watch companies like Vacheron Constantin experimented with various colors and unique case designs, much different from traditional circular watches. In 1972, the French Government awarded Vacheron Constantin the Diplôme du Prestige de la France, recognizing his 'Prestige' model with an asymmetrical curved case featuring an oval movement. This model was emblematic of the 1970s style of individuality and experimentation. The Prestige was famous for housing the world's thinnest mechanical movement at the time, the Vacheron Constantin Caliber 1003, measuring only 1.64 mm in thickness. The case design operated within the bounds of the 'Golden Ratio', a mathematically perfect design used by famous designers like Pythagoras and Fibonacci. The design of the Vacheron Constantin Prestige was calculated to equal the Golden Ratio. Vacheron Constantin won the award for achievement and contribution to French heritage in 1972, thanks to the combination of the Caliber 1003 and a mathematically perfect case design.
