Here is a stunning and very rare, all original Longines Conquest Calendar Automatic from 1957. The silver dial is in excellent condition, with a steel Longines winged hourglass logo and black lettering. It has a brushed chapter ring with spaceship steel hour markers at the poles and double wedged steel hour markers in between. The dauphine hands are in very fine condition. The steel framed window at 3 o’clock displays the date, which can be semi quick-set by first turning the hands through midnight so the date changes, then immediately turning the hands backwards to 21:00 and then forward through midnight again. Repeat as necessary.

The stainless steel bezel is in fine condition, with light overall wear such as at around 6, 9 and 11 o’clock. The stainless steel case with heavy lugs and the original crown is in very fine condition with only light overall wear, perhaps most prominent a couple of small nicks on the left case side. The stainless steel case back has a slightly worn Conquest medallion and is in fine condition with some overall wear. The case does not appear to ever have been polished.

The watch comes on an after market leather strap and buckle of good quality.

Inside the watch, Longines’ legendary 19ASD movement beats strongly and accurately to within about +-12 seconds per day. The watch was fully serviced in June 2026 and comes with a 12 month warranty on its proper mechanical functioning.

Vintage Longines watches were always known for their great design and outstanding mechanics, and this one is a supreme example of that legacy. This is a watch that looks fantastic on the wrist and it will add to any vintage collection.

Our watches are delivered in a luxury wooden watch box, fully serviced with a 12 month warranty that covers the mechanical functioning of the watch under normal use. We offer 14 days full return rights and are very proud of our reputation for outstanding customer satisfaction.

NB! Note that we are based in Switzerland and that the buyer is responsible for any import fees their country may impose on a purchase from abroad. Ask us if you have any questions.
