I’ve been lucky enough to have a few Longines at the shop, and all of them have been super unique, but there’s no question that this Ultra Chron HF was way ahead of its time!


Mechanically speaking, most watches produced TODAY do not have a high-frequency movement…


This Ultra Chron HF, with its cal.431 automatic movement however, has an incredibly smooth 36,000bph sweep!  That alone is something you just wanna stare at!


With a very sporty cushion case, stout block indexes, applied “Longines” font, and an applied Ultra Chron insignia- This Longines is an absolutely impressive addition to any vintage luxury watch collector!
