The British-Swiss brand shook up the industry when it first unveiled the original Twelve integrated sports watch two years ago, and it’s been constantly expanding the line ever since.
The original Twelve measured 40mm across and came in both stainless steel and titanium variants. This was soon followed up by smaller case sizes of 36mm and 38mm in steel (plus 36mm titanium versions, which have since been discontinued), the luxe skeletonized Twelve X in steel and titanium, and the literally insane C12 Loco flagship with its in-house, openworked movement.
Now, the Twelve line has expanded once again with a brand-new model that brings a dose of debonair flair.

Thin is in
The new Twelve is the Twelve 660, a name derived from the watch’s exceedingly thin 6.6mm-tall case. The previous standard-bearer for Twelve thinness was the Twelve (ti), which comes in at a hair under 9mm. As an owner of that watch, I can say that it wears extremely thin, so it’s hard for me to imagine a version that’s nearly 50 percent thinner. And yet, here we are.
The Twelve 660 achieves its thinness in part through its choice of movement: the hand-wound Sellita SW210-1 b. The Swiss-made movement measures just 3.35mm thick and yet has a decent power reserve of 42 hours and beats at a standard 4Hz. The movement is visible through a sapphire caseback and is quite nicely finished, with the highlight being a custom-designed train bridge that’s exclusive to the 660.
