Help with new PAM

[DINGER]

Good evening/morning everyone depending on your location!

Ever since I bought my PAM312 I've lusted after another. My 312 gets more wrist time than my GMTIIc and Daytona combined.

Top of my list is the PAM335 but I beleive this retails for about £12,000 in the UK which is way out of my budget unless I trade in one of my other watches which I'm reluctant to do as they all have sentimental value (30th birthday and wedding being amongst them).

I've just seen the PAM441 Ceramica which looks fantastic, has this been released yet in UK? I can't find any info online about release date or price. I need to take a trip into London to visit some dealers but won't have time for a month or so. Can anyone give me some detail?

I also really like the simplicity of the 422 and 423, I think I have the wrist size to pull off a 47mm watch but again can't find much info. Are these available in the UK yet and any idea on price?

On another note, a friend of mine was talking to me about the PAM392 which appears to be identical to my 312 other than it's a 42mm and not a 44mm, are there any other differences?

Apologies for all the questions, I know I should go speak to some dealers but I don't want to go in blind, like to find out some info first.

Thanks

Chris
