Description
The AIRLOCK Eyeglasses Seven-Sixty 217 604 are a premium lightweight rimless optical frame from the Airlock “Seven-Sixty” collection, designed around the brand’s signature philosophy of minimal weight, screwless engineering, and modern titanium comfort.
The Seven-Sixty 217 features a rimless rectangular silhouette, giving it a sleek and highly minimalist appearance. The absence of a traditional full frame creates a lighter visual profile while maintaining a professional and contemporary aesthetic. This style is especially popular among users who prefer subtle eyewear that feels nearly invisible during wear.
The “604” color code is identified as a burgundy finish, adding a refined and slightly expressive tone to the otherwise minimalist titanium design. Retail listings describe this variant as a warm burgundy metallic color that adds personality without overpowering the frame’s clean aesthetic.
