With Patek Philippe Extract from the Archives confirming production of the present watch with black dial and applied white gold indexes in 1977 and its subsequent sale on 13 February 1978.
To the best of our knowledge, this watch has never been offered in public before.
The legendary Nautilus collection was introduced in 1976 when Patek Philippe was looking for a strong design of inimitable personality. An inspiration for such a timepiece soon emerged: The universal shape of a porthole found on virtually all maritime vessels. Since then, the Nautilus has established itself as a classic elegant sports watch and the original reference, 3700/1 such as this watch, is one of the most sought-after timepieces at auction.
For a reference 3700/1 in 18K gold see lot 367 in this sale.
Ref. 3700/1 is described and illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, p. 231.
