I saw Spectre last night as well (at an Omega-sponsored preview) and got a brief glimpse of the watch Bond was wearing after his Seamaster 300 was
[*****SPOILER ALERT!!!!!*******]
detonated.
[***** END SPOILER ALERT*******]
The post-detonation watch that Bond wore was on a stainless steel bracelet, and in that brief glimpse my fleeting impression was that the watch may have been a Planet Ocean like the one worn in Casino Royale, Quantum of Solace, and Skyfall. However, after consulting Dell Deaton's uber-authoritative web site
www.JamesBondWatches.com it's clear that the second watch that appeared in Spectre is indeed the blue-dial Aqua Terra (not the Spectre LE version of the Aqua Terra).
