Innovative use of Artisanal Technique Transforms Hardest Working Frame Component; The defining feature of the sunglasses in the new Serengeti Signature collection is a hinge made with an ancient practice known as lost-wax casting. Sometimes referred to by its French name, “Cire Perdue,” – this method is often used to make fine art and jewelry. A labor intensive, multi-step process that requires the use of the finest metals and alloys – in this case, copper beryllium – lost-wax casting allows for a level of finish detail nearly impossible to achieve with more common mass- production techniques.

Rather than more conventional attachments, Signature hinges are finished with durable stainless steel Torx head screws. With a much more precise interface with the tightening tool, Torx head screws have two distinct advantages over slotted screws commonly used for this type of application. First, stripping, which can make removal of the hinge screw extremely difficult, is virtually eliminated. Next, greater torque can be applied during the installation process, resulting in a more secure connection, significantly less prone to loosening over time and repeated use.

The main frame structure and temples of the three initial Serengeti Signature models, Brera, Isola and Verdi are made with Grilamid TR90 nylon. Prior to assembly, the frame components are hand sanded for a lustrous finish that feels soft to the touch and complements the craftsmanship of the hinges.

“Hinges – while performing an important function – aren’t typically the most noticeable component of sunglasses,” noted Dani LaGace, Global Director of Eyewear. “That we’ve lavished so much attention on this small but critical part is an indication of both our attention to detail and commitment to being a leader in the art and science of making eyewear.”

All Serengeti Signature sunglasses are fitted with Ultra-Light glass lenses that are 20% thinner and lighter. Made with borosilicate optical glass from Corning®, these lenses are chemically tempered for scratch and impact resistance. Available in several versatile tints, the lenses incorporate three technologies to optimize common interactions with light, reducing eye strain and improving visual acuity:

Photochromic – Pioneered by Serengeti, this technology instantly adjusts tint to compensate for changing light conditions

Spectral Control – Manages specific colors in the light spectrum to sharpen contrasts Advanced Polarized Surface Technology – a proprietary process delivers up to 98% polarizing efficiency and removes any possibility of delaminating.

Available early 2014, each of the three initial Serengeti Signature models will be offered in several frame colors with mildly contrasting hinge finishes and are priced at $269.99.
