Description
A honeyed, light yellow frame indoors. A deep tobacco brown outdoors. The C7 is the warmest and most vintage-spirited colourway in the 52613-2 series — and the only one fitted with brown photochromic lenses, for a golden-toned view that flatters everything you see.
Key Features
- Warm Honey-to-Brown Transition: the frame deepens from light yellow to a rich, leather-like brown in UV light — a natural amber-toned evolution instead of a stark colour switch.
- Brown Transition Lenses: the nylon lenses shift from clear to warm brown, the classic driving and outdoor shade known for enhancing contrast and depth perception.
- True Vintage Character: honey crystal and tortoise-adjacent tones make this the most retro pair in the series — think 1950s keyhole round, updated with smart photochromic technology.
- Golden-Hour Vision: brown lenses deliver a warmer, more comfortable outdoor view than grey, especially in variable light.
- Lightweight All-Day Build: just 28.5 g in injection acetate with a 49-22-145 retro round fit for men and women.
Description
Every collection needs its connoisseur’s choice. For the 52613-2 series, that is the C7. Indoors the frame is a translucent light yellow — the honey-crystal tone that vintage eyewear collectors chase, warm against the skin and beautiful in natural light. The clear nylon lenses keep your indoor vision neutral and precise.
Step outside and the pair warms through: the honey front and temples deepen into a mature tobacco brown, while the lenses darken to the series’ signature brown photochromic shade. Brown is the classic connoisseur’s lens colour — it boosts contrast against green and blue landscapes, softens harsh glare and gives everything a gentle golden warmth. Golfers, drivers and sailors have preferred it for generations. The retro round silhouette with keyhole bridge completes the vintage picture.
Perfect For
- Driving and road trips: brown lenses are the traditional driver’s choice for contrast and comfort.
- Autumn and winter light: honey and brown tones match cold-season wardrobes.
- Coffee runs and bookshops: warm vintage character indoors and out.
- Golf, fishing and outdoor sport: brown’s contrast boost shines in green natural environments.
