This Le Coultre is an automatic watch with a winding indicator window just below the 12 o'clock position so that you can refer to the amount of reserve time you have on your mainspring. It is in excellent condition in every regard! Just look at the case and dial, they are in great condition. The case is yellow gold-filled and it measures 33mm in diameter by 40mm from lug to lug. This watch represents the pinnacle of watch making, circa 1951, at Le Coultre, long before Jaeger came around! Yep, they could compete with any watch company in the business at this time and you can see why! This is a watch with a technical complication that adds a new level of service for the consumer and, because it is a "Bumper Automatic" every motion of your wrist (while you are wearing it) winds the mainspring. You can visually see what power reserve you have at a glance. The dial is just beautiful in its simplicity and is complimented by the arcaded seconds track and the red sweep second hand. It's subtle yet provocative! Ha! Our watchmakers have it timed to a very fine standard and it is keeping time like the day it was made.Remember all of our watches come with our famous one year warranty for parts and labor so that you may purchase a watch from us with complete confidence. Don't miss this fine example of the watchmakers art!
