Extremely rare Breitling full calendar watch with moon phase, all parts in 100 % original condition, screwed steel casing with 18 kt genuine gold plating, diameter without crown 29 mm A maximum of 4-6 pieces of this watch exist worldwide Since counterfeits with the Valjoux 90 caliber are always on offer for a low price on the internet, the genuine watch with the very rare and high-quality Valjoux 89 is completely underrated and undervalued. This is one of the rarest Breitling watches. The actual value of the watch is at least €5,000. Fully functional Valjoux 89 caliber with reference 244-24, still gold-plated with full calendar and moon phase display. New old stock, the watch runs smoothly and all the settings work, including the pushers. I would suggest getting it oiled and timed since ita has been sitting on an envelope for a lifetime, it attempt to gain a few minutes per day. Hand-wound full calendar watches by Breitling were always marked with the chronograph serial number system, therefore it has the serial number 796564. This is from the year before the switch to the new inscription "B Breitling", still without "Geneve" on the rear lid. So a quite special watch from the transitional period. A new leather strap fitting a wrist up to 8 inches. Shipped insured.
