Its self-winding caliber 240 Q with micro-rotor drives the perpetual calendar and moonphase with the clarity that made this model such a lasting benchmark. The 18k yellow gold case measures 36mm across and 8.8mm thick, notably slim for the complication and composed enough to disappear under a cuff when needed. A silver dial keeps the watch as calm as its architecture deserves. In the 3940, Patek Philippe made a perpetual calendar that feels complete, and that completeness still defines its appeal. ## Appearance - **Colors:** silver - **Materials:** Yellow Gold, alligator ## Categories - **Categories:** Home > Patek Philippe > Perpetual Calendar > 71467 ## Additional Attributes - **box:** Patek Philippe Box - **dial:** silver - **model:** 3940J Perpetual Calendar 18K Yellow Gold Silver Dial - **width:** 36, 36mm - **height:** 36, 36mm - **diameter:** 36mm - **movement:** Automatic - **condition:** Like New - **reference:** 3940J - **thickness:** 8.8, 8.8mm - **certificate:** Original Certificate, Service Papers - **depth rating:** 30m - **original box:** 1 - **stock number:** 71467 - **case material:** Yellow Gold - **complications:** Moonphase, Perpetual Calendar, Moonphase, Perpetual Calendar - **strap material:** alligator - **reference number:** 3940J ## Enrichment - **Type:** watch - **Type Synonyms:** wristwatch, timepiece - **Gender:** unisex - **Age Groups:** adult - **Tags:** perpetual calendar, moon phase, 18k yellow gold, alligator leather strap, analog display, luxury watch, silver dial - **Styles:** classic, formal, luxury - **Colors:** silver - **Color Families:** Gray - **Category Path:** Apparel & Accessories > Jewelry > Watches > Fine Watches - **Band color:** Black - **Band pattern:** Solid - **Case color:** Yellow - **Case pattern:** Solid - **Dial color:** Silver - **Dial pattern:** Solid - **Watch case shape:** Round - **Watch display:** Analog - **Watch features:** Date Display, Moon Phase Display, Perpetual Calendar - **Watch material:** Leather, Metal - **Watch movement type:** Automatic - **Canonical Brand:** Patek Philippe ## Images - ![Image 1](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/b085253111b1336918ca3f384131ee48.jpeg) - ![Image 2](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/74f90923d0c482e29070197fe91b5e6e.jpeg) - ![Image 3](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/ab7e33001d1fecdaf5b67d4baf7ee903.jpeg) - ![Image 4](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/caa930aa7cdf2d1b3a488b0783bdcefd.jpeg) - ![Image 5](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/c25af056140ba6c76eec34024bad746e.jpeg) - ![Image 6](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/2cfacc113069e94dd137d637b1523b25.jpeg) - ![Image 7](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/21776df8322b20a5103ecfc6304f0bea.jpeg) - ![Image 8](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/f7c07d1bb80272124754e7a37ecd7d54.jpeg) - ![Image 9](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/05815c0baa59c1de545bf9a0930fb7b6.jpeg) - ![Image 10](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/fefb1246595a1c7ec8cd035c9651a212.webp) - ![Image 11](https://cdn.octogen.ai/79a4e8bf0f2f8b0ab69a067d5559d190/049dbf85d90ec23ac332751dac6ca49b.webp) --- *Source: cosimo.shop | Product ID: d6c05b2f-b42c-53d9-866c-9db7537a14cc | Canonical URL: https://cosimo.shop/product/patek-philippe/3940j-perpetual-calendar-18k-yellow-gold-a64964b5-4fb5-4fc9-b94e-6d4c78359560*
