Very Rare JLC Pendant-Watch in Superb Condition

Very rare collectors timepiece, made by Jaeger LeCoultre, in fantastic unpolished condition -- stunning!

This is a very unusual pendant watch in 18K yellow gold. Glass and case is without any visible scratches or damages. The faultless structure on the case front and back, tells that this watch was never polished, but is in original condition -- and this condition would be breath-taking for a 25 years old watch. But this item is more than 50 years old...
