Hey, the name of the thread says it all... What is the difference between the 146H and the 146HP? Thanks a lot!
Not sure what's the difference between the 2.Am also curious. My A277 has the 146H which I believe came first before the 146HP. Maybe it lets the wearer lasts longer on a full wind. Sorry I meant the watch.
Nothing at Ranfft on these, but from something I read elsewhere... accuracy not guaranteed... it's the internet after all. HP has a different type coil (flat), balance wheel, regulator, and perhaps other parts. HP also does not use incabloc, but another version of shock resistance.
Here's the 146 HP in my A277 - LouS' photo from when he was selling it to me. You're spot on Darlinboy, it has Kif shock protection and a flat hairspring. Does the 146 have an overcoil?
