Reference 3700 was equipped with caliber 28-255 C based on a Jaeger- LeCoultre ébauche, the best thin automatic movement at that time. The cases were manufactured by Favre-Perret and they existed in stainless steel, steel and gold, 18k yellow, white gold and platinum and the dials were hand made by the highly skilled Stern Frères creators.
In 1980 Patek Philippe started to create cases and bracelets in their Ateliers Reunis workshops and the Nautilus changed its reference number to the new 3700/11. The new stainless steel which was being used is called "Chrome-Nickel-Molybdenum steel" and the bracelet's deployant clasp has been reduced to 16mm, from 18mm of the previous reference.
The production estimate of reference 3700/11 in stainless steel is approximately 1,200 pieces. Furthermore the present example is offered fresh to market and in superb condition.

The present watch is consigned by the original owner, who purchased it in 1987 from a Swiss retailer while vacationing there with his wife. He has worn it sparingly over the years and always had it serviced by Patek Philippe in Geneva.
