The number 4810 refers to the height of Mont Blanc in metres and is interpreted as a homage to highest aspirations; the 888 variant stands as a triple eight in Asian symbolism for highest happiness and marks the more exclusive edition. 888 models are often of solid precious metal, additionally provided with gemstones or special decoration and correspondingly more expensive. Each Patron of Art edition also has its own nib engraving, by which the model can be identified. Limitations arise both quantitatively (number) and temporally through production limits and meet collectors' wish for 'something special'; as sole purchase motivation, however, limitation does not count.
