Noob question on parts

[srleadjb]

Hi guys (and gals?)

So I'm obviously new here. I've been on vacation for December and had nothing but time to play on this site. I've been diligently using the search function to educate myself on the Pam line-up and have already shot from the hip, ordering a Pam 288, and a 177L. I'm currently awaiting those. In my hast and true to my impulsive tendencies, I found a local dealer in my area. I bought a Pam 186 (Arkos) and a Pam 090 from him to ease the pain while awaiting my overseas purchases. Since I bought those last week, I've learned a lot and I now realize they are not the best reps. The Arkos for instance, looks ok but the bezel doesn't lock on N/S/E/W, instead on the in between notches??? Also, it has the Arkos dial but the North Pole case back (doh!) The Pam 090 looks ok too but has the date push button on the left side of the case at the 7 o-clock (doh again!) Lol, I had no idea what to even look for when I bought these...........

Anyway, this site is awesome and I'm so excited to have found a new hobby. So, as the topic description says, I'm wondering if there is a resource somewhere or if someone can sum up quickly as to what parts are interchangeable among the Pam watches. I understand the basics, as far as case size differences and the different movements being used for different functions but if we are talking within the same model line-up and size, would most of the functions be interchangeable? For instance, if I want to use the two reps I bought as "parts" for a future project and since they are both Luminor (44mm,) would the two cases be the same? Case guards and case backs seem to be the same. What about the front glass (size wise) and bezels?

I really have tried to answer all my own questions but I have not found anything that spells this out. Thanks for any knowledge you may share!
