1940 Longines Vintage Mens Large Art Deco Watch - Platinum & Diamonds


Item No. 7820

Today's offering showcases this large and very striking Longines mens wristwatch in platinum with diamonds made for the U.S. market.

Its diamond bejewelled case and dial are suggestive of the glittering elegance associated with 1930's and 40's American high society.

Its long, curved platinum case has an elegant ribbed design, later set with twenty-eight full size diamonds. Complementing the case is its striking Art Deco dial (face) originally Longines factory set with diamonds.

As fine on the inside as the outside, it is powered by the under appreciated, very well-designed and finished caliber 9L engine. The 9L is on par with the rectangular movements found in some watches from even more prestigious makers at much higher price points, and this early 9L is factory equipped with a regulator whip, the first one we can remember seeing.

It is a glittering watch with a regal style - it captured the essence of the rewards available to those who through hard work and dedication achieved a position of leadership in law, medicine and business.

Its opulent 43mm long case has rippling to the sides and wear to the top of one lug but still presents nicely on the wrist. Its impressive diamond dial has just been restored by one of the leading dial experts in North America.

One of our watchmakers has freshly cleaned and oiled the movement and installed a new mineral glass crystal. It is running very strong and true...amazingly after over 80 years it is keeping time on par with a brand new Longines in our testing position.

For the finishing touch we have equipped it with a brand new Teju lizard strap making it ready for immediate enjoyment.

Included with the purchase is a one-year international warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.

Longines is known for creating some of the most technically innovative and attractive timepieces in the world. Once worn by Humphrey Bogart, Richard Byrd, and Charles Lindbergh, these pieces are sought after by collectors and anyone desiring to wear a true high-grade wristwatch.
