Oops, jumped the gun...
...on the purchase 
I think the only major change on that model over the years would be the strap changing system.
The older models used screws to hold the strap / bracelet in place and you would require a screw driver to remove the strap. I believe with the J series they switched to the newer version of the strap changing system where there is a recessed button that you push in with the supplied tool to release the pin that holds the strap in place. It is a slightly quicker method for changing the straps and shows the ever growing technical development of the brand. For me, either system is fine as I have watches with both.
It is a great looking watch. I started my obsession with Panerai with the Pam 50, which was the black dial, 40mm on the bracelet. At the time, I had a similar feeling about the size of the watch, but I really loved the style and felt that I could make the 40mm work. Well, my wrist size hasn't changed but I'm now wearing 44mm and 47mm watches without any concern. As Stephen said, you might be moving up in size once you get used to it 
Good Luck.

With Panerai, you can't ask all, you have to discover, then, if you don't get something, ask. The discober ( hence, the Homework ) is necessary. 1st question: As for a 40mm Panerai watch, won't I regret it? The Panerai DNA is 44 mm minimum. All those ( we...

If that's the case, I would give up. I am not interested enough. Sorry. Did I ask so many childish questions to touch some people's nerve? If so, I apologize but I didn't mean to. I had done some homework and then came here, but apparently it was not...

Knew you would one day come and join us! Afterall, who can really resist the Powers of Panerai! LoL I still remembered when I brought you to the boutique here and you weren't even one bit interested! But as Asimut said it, stick around this lounge, and yo...

Knew you would jump on my post! Interesting that we are so different, although similar in taste. You like 40mm or larger, I like less than 40mm. We both like same brands, but never the same medel! Not so fast... I am not sure I will dig deeper in Penerai,...
Yup, my bad. It is...

Yup, my bad. It is 049... I knew I would get help from a kind Panerist like you! I very much appreciate it. And.... I have not yet purchased it yet :-) So, is there signifcant difference among the "series"? This model has been out there since 1999? a...
