This is my first time starting a post because it is rare I can't find information right away here on WUS from people who have had the same questions. I've been learning tons from the forums over the past several months. After seeing the Hamilton chronomatic w/ cal. 11 on worn&wound I've become borderline obsessed with vintage chronos. I've yet to pull the trigger on one as many are just outside my reach financially (although my definition of an affordable watch has changed drastically in the past months!).
Anyways, I've been watching a Wittnauer Chrono Professional (World Cities) on eBay that has the Cal 14Y movement. The only information I dug up was that it was a modified "Landeron 249" movement according to someone on the sales forums. After searching for Landeron 249's I think that may have been a typo as little to no information showed up on the 249. So is the cal 14y a modified landeron 248? If not what movement is it? Is that a good reliable chrono movement? Easy to get parts? How does it compare with the valjoux 773X movements?
Any information on the movement or further info on Wittnauer chronos of the 60s/early 70s would be greatly appreciated! I have thoroughly appreciated the depth of knowledge here on the forums...thank you!
