May I ask how long the service took and when was the last time you had it serviced? Just curious on the maintenance schedule of one of these quintessential Pateks

3940 is not anymore in PO catalogue since long but the 240Q caliber inside is still in production and widely used so can be serviced with no major problems. We’ll see what Roland says...

...gave me the impression that they were the typical sunk sub counters of the fist generation. Wrong assumption 🀭

I have seen one of these on Philippe Stern’s wrist a few times so you are in good company. Glad your baby is back all serviced and ready for the next few years service. Enjoy. Miles.

Previous owner service it 8 years ago. But generally for my watches, I send them for service in between 5 to 7 years. Watch with more wrist time, I usually send in about 5 years as per manufacturer recommendation.
