Tom Ford Snowdon FT0237

Tom Ford announced that James Bond (Daniel Craig) wears Tom Ford Snowdon FT0237 sunglasses in SPECTRE.
The sunglasses are worn in the Rome funeral scene.
There has been some debate among fans what is the correct color. The color of the glasses was said by some Tom Ford boutiques to be Shiny Black 05B, but it is actually Havana (sometimes named as "Tortoise" or "Brown") color code 52N (see new image from Rankin's Behind The Scenes book on the left) with the standard grey lenses, which seem slightly brown in real life and on the photos. This was also confirmed by the Christie's Auction in February 2016, where a Hanava pair was offered, size 50, one of four pairs worn by Bond on set in Rome.
Update 2018: Tom Ford mentions now that 52N is "Dark Havana" and a new "52N2" is "Havana", but we assume that the 52N is still the same as the one in the film.
There are two sizes: 50 and 52, Bond is wearing the smaller size 50.

Tom Ford Henry
Bond wears another pair of Tom Ford sunglasses in SPECTRE, the Henry Vintage Wayfarer model.
This is the third movie in which Bond wears Tom Ford sunglasses: see also the Tom Ford FT0108 in Quantum of Solace, which were released in a special James Bond branded case, now sold out, and Tom Ford Marko FT0144 in SkyFall, which are still available.
