Longines Ultra-Chron - References, Prices and Owners' Reviews

This watch, water-resistant to 300 meters, is extremely elegant. It offers very good readability day and night. In full sunlight, the sapphire bezel is magnificent with its red indexes. In the shade, the touches of green luminescence are most beautiful. Its precision is excellent, measured between 0 and +2 seconds per day on my copy.

I succumbed to the shape of this watch that I find very original. While listening to Julien in an episode of Petites Montres Entre Amis, I told myself that it was time for me to look at vintage Longines more closely and in particular the Ultra-Chron collection recognized as one of the very first watches equipped with a 5Hz caliber. While searching on the various second-hand watch sales sites, I discovered this one with a unique shape! The hands are original - if we refer to the ads of the time - the striated dial, the crown at 4 o'clock gives it an asymmetrical side... It has just joined my asymmetrical collection with the Zodiac Olympos and the Omega Constellation D-Shape! It would have been even more successful without the date which impacts the purity of the lines... Note an outdated configuration with a monobloc case which opens by removing the glass... I'll leave that to the watchmaker who will service it in the coming days 😎

A watch that combines charm and period know-how, this Longines Ultrachron ref 7826 dating from 1973 reminds us that sometimes certain vintages deserve a lot more attention. The horns are very angular with a slight chamfer on the inside. The rather thick stick indexes have multiple facets, the dial is cream-colored and is crossed by a line called "target", the Longines logo and the ultra-chron symbol are applied. The domed glass obviously gives us the feeling that the edge of the dial is curved, which it is not. The case, case back, hands and indexes are in 18k rose gold, which contrary to appearances remains rather discreet and not flashy surely due to the very light brushing of the case. To finish it is a very classy watch, that I wear sparingly during special events, the noise of the caliber 431 very singular and hypnotic is similar to a small "machine gun". It did not take less to become my dress watch par excellence.
