I have it from a dealer in vintage watches that the quartz is one of the less popular models though quite rare by production numbers. I just bought one of the first produced in like new condition and paid 2500USD for it with a similar warranty. My friend told me dealers usually look to buy them at anywhere from 1500 to 2000 USD or less depending on condition, eye appeal and rarity. Enjoy your watch as I hope to enjoy mine.
