Question about a Radiomir Black Seal 183 G

[agreenspan]

Hi everyone!
Here's a newbie question for you. I have an opportunity to purchase a PAM 183 G. I understand that the "G" series of the Black Seal are the first modern ones, and are different from all the rest to come because of the placement of the words "Black Seal" at 6 o'clock on the dial. I understand the Movement is decorated differently also.
1. I was just wondering if there is any benefit to getting this Radiomir as opposed to a more recent one.
2. Has the movement or anything else been improved over the last few years?

I read that 'collectors' might like the G series one in the future because it looks different, but right now it seems like the same price as any other series.

Anyway, Thanks for all your help and insight...
Stephen.
