Cutler and Gross 1431 Titanium Optical
Titanium Optical Frame with Engineered Cutler and Gross Precision
The Cutler and Gross 1431 Optical balances architectural sharpness with mechanical elegance in a way that feels deeply intelligent and beautifully controlled.
The geometric square silhouette is clean, disciplined, and highly considered, carrying the unmistakable Cutler and Gross tension between intellect and individuality. The frame feels sharp without becoming clinical, elegant without ever slipping into formality.
Handcrafted in Japan from pure titanium, the 1431 Optical feels exceptionally refined in the hand and almost weightless when worn. The construction is minimal in weight, but immense in precision — every surface, transition, and proportion resolved with obsessive attention to detail.
Much of the design language draws from the sculptural curves and engineering confidence of British supercars from the 1960s and 70s. The Oyster pin nose bridge references vintage front grills, while the flowing temple tips echo the lines of classic automotive bodywork. None of the detailing feels decorative for its own sake. Every element exists as part of the frame’s underlying structure and identity.
What makes the 1431 Optical especially compelling is its restraint. Despite the extraordinary craftsmanship, the silhouette never demands attention loudly. The frame assumes the right people will notice the precision without needing explanation.
The clear optical lenses leave the expression fully exposed, reinforcing the composed and self-assured nature of the design. Nothing hidden, nothing softened — just structure, proportion, and presence carried naturally through the face.
The Knightsbridge Green collection is produced in highly limited quantities, with each frame individually finished with its own bespoke edition number, giving the optical the feeling of a collector’s object rather than a trend-driven accessory.
The 1431 Optical doesn’t feel nostalgic or futuristic. It feels permanent — engineered with the kind of emotional precision that rarely exists anymore.
Ideal for:
- architectural optical styling
- refined titanium eyewear collections
- collectors of highly crafted frames
- wearers looking for disciplined design with emotional depth underneath
The overall effect feels exact, intelligent, and unmistakably Cutler and Gross.
CUTLER AND GROSS — precision becomes unforgettable when it carries soul with it.

Size and Fit
I understand the importance of a proper fitting frame. Not every frame fits every face, which is why we have a wide selection of frame sizes to choose from.
There are no rules – just guidelines we suggest to help you find frames that not only look great but fit perfectly.
HOW WE SEE YOU
Size definitely matters. We determine size by the width of your face. We offer multiple sizes so that you can find the right frame for your face.
If you already wear glasses, we recommend looking at your current pair as a size reference. If you still have doubt we are here to help you with professional advice.
BRIDGE – INTERNATIONAL OR ALTERNATIVE/ASIAN FITTING
Acetate nose pads: Made from Italian or Japanese acetate. Comfortable, classic fit. Recommended for those who prefer the look of acetate.
Metal nose pads: Made from silicone or ceramic. Soft, flexible, anti-allergic. Recommended for those needing additional support for less prominent nose bridges or more prominent cheekbones.
FIND YOUR FACE SHAPE
Oval
Balanced and slightly narrow, the oval face is a canvas for experimentation. Almost any silhouette will look good on you. Luxury lies in the choice.
Heart
Wide forehead, high cheekbones and a narrow jawline. This shape is expressive and romantic. Choose a sharp-edged or gently curved cat-eye shape or a balanced aviator shape that softens the contrast and emphasizes the proportions.
Square
A strong jawline, higher forehead, and symmetrical brow line characterize this sculptural face. Choose rounded or elliptical frames to soften the angularity and enhance natural strength with graceful restraint.
Rectangle
Long and slender, with delicate lines. Here, it is worth choosing frames that give width and dimension to create harmony. Oversized or deep-set profiles bring visual balance to the more elongated shape.
Triangle
Defined by a more pronounced jawline, a finer forehead, and an elegant contrast between cheekbones. Choose round or square frames with sharp lines that harmoniously balance the proportions.
Round
A full face and delicate contours radiate warmth and symmetry. In contrast, square frames elongate and define the face.
There are no rules – just guidelines. Explore, get inspired and choose frames that make you feel confident, happy and most importantly, yourself.
