PAM311 & PAM275 Question

[lowmandfl]

I really love the throwback look of the 1950 case design with the dome crystal, and I've been looking at potentially getting either a 311 or 275. They have the same P.2004 Monopulsante 8 day movement. I know they aren't hugely popular watches (most seem to prefer the 233 design), but I wanted to ask about movement issues and if it's really something to be concerned with.

I've done a fair amount of searching and reading, but haven't found a lot of information. I know there were some reports of the PAM233 having issues with the power reserve hanging up on some of the dot dials, and I'm assuming there are similarities in the movements of the 275/311 & 233 as they both share the 8 day. Is this something to be overly concerned with? I'd prefer not to have to go down the road of servicing, but if that has to happen are those issues pretty easily resolved by a Panerai service?

Does anyone have feedback, thoughts, or anything to look out for? Really appreciate it!
