A true icon of 1970s watch design, this Patek Philippe Nautilus 3700/1 was produced in 1977 and sold in 1978, as confirmed by the accompanying Extract from the Archives. It comes with its original cork box and is presented in excellent overall condition.

The stainless steel case remains sharp and well defined, though it has been polished in the past. The original steel bezel is also in excellent condition, retaining strong angles. The original sigma tritium dial shows slight oxidation and great character, while the hands have been replaced with later luminova service units. The integrated bracelet is tight with no stretch, and both the clasp and crown are correct and matching.

Offered in perfect working condition, this is a beautiful example of the early Nautilus 3700—a cornerstone piece for any serious Patek Philippe or Genta-era collector.
