The decision to use this precious material was based upon the objective to combine an extremely high-end product meant for the luxury world and its undeniable sporty nature.
This 6612 reference, manufactured in 1958, is one of only two examples known in platinum. Most fascinatingly, they have consecutive case numbers underlining the rarity of this reference
cased in platinum. The other example is illustrated in "100 Superlative Rolex Watches", by John Goldberger, page 174-175.
