As aligoat said... Hollow is *correct* for the watch, in terms of what the genuine came fitted with.
However, your personal preference may vary. Some people like the solid links as they feel a bit more substantial; I know a couple of gen owners who greatly dislike the hollow links.
BTW, Rolex has been slowing converting over to solid link bracelets as well. For solid 18K (not TT), links have been solid for some time now. For SS, the change started with the 16622 Yacht-Master and then with the 116520 Daytona. Other models, like the new TOG, etc. have been going solid as well.
