With a production of the reference spanning 22 years, early examples of the reference featured cases made by La Chaux-de-Fonds based master casemaker Favre-Perret and was available in stainless steel, two tone yellow gold and stainless steel, yellow gold, white gold and very few examples in platinum. In 1980, Patek Philippe started to manufacture their own cases and bracelets and those examples were referenced 3700/11. With its aesthetics kept very similar to its early examples, the later examples were fitted with a narrower bracelet measuring 14mm at the end in comparison to its previous measuring 16mm. The dials were handmade by Stern Frères with engraved stripes to achieve its desired ribbed appeal. The smoky bluish grey hue is achieved by applying a “petrol blue” base, followed by spraying a matte black layer and finished off with “Zapon” vernis finish.

The present example ref. 3700/11 is one of the rarest iterations of the reference. Encased in a two tone 18K yellow gold and stainless steel case, it is estimated that only 200 examples were ever manufactured by the firm with stainless steel examples estimated at 1200 examples. The present example is presented in attractive overall condition and is presented with a Patek Philippe presentation box and an Extract from the Archives issued by Patek Philippe confirming its date of manufacture in 1982, stainless steel and 18K yellow gold case with bracelet in stainless steel and 18K yellow gold.
