The new 27º Air glasses from TAG Heuer get their name from the angle at which the arms fold due to the ‘invisible 27º hinge’ in the titanium frame.

TAG Heuer will make available a myriad of lens choices, including six colour options and three shapes, including a photochromic option with five layer anti-reflective coating. The lenses are made from Makrolon poloycarbonate which they claim are ‘unbreakable’.

The 27º Air also features an adjustable soft touch nose pad and two adjustable end tip options to customize the fit.

Prices range from £111 to £228 depending on lens/frame combination.
