« At Fashion Week, style speaks in clean lines — a truly unisex watch is the sharpest punctuation. »

During Fashion Week, there’s a moment when noise gives way to light: silhouettes cross, fabrics catch the flash, an oversized blazer brushes past a razor-cut suit and vanishes backstage. In a world where everything is intentional, the strongest accessory isn’t the loudest one — it’s the one that signs. The BOY·FRIEND H4878 does exactly that. It doesn’t beg for attention; it draws a line. Steel rectangle, deep black dial, controlled shine: a modern presence that doesn’t need gendered codes to feel desirable. The BOY·FRIEND collection was created in 2015, built on Chanel’s long-standing instinct for twisting the masculine wardrobe into something effortlessly chic and modern. The name is a knowing wink: a watch you could “borrow”, or have borrowed from you. It’s a design language of purity and architecture — naturally at home in the rhythm of fashion seasons. 

The BOY·FRIEND line debuts in 2015. The H4878 reference — commonly associated with the “Tweed” execution (steel tweed-motif bracelet, black guilloché dial, quartz) — is typically seen with production years listed from around 2016–2017, with dated examples appearing through more recent years on the market, pointing to a long-running presence for this reference. 

The 34.6 × 26.7 mm steel case offers confident presence without weight — one reason it reads so naturally as unisex. The black guilloché dial stays crisp and graphic, while the date at 6 keeps the design balanced. A high-precision quartz movement brings everyday freedom: dependable accuracy, instant readiness, no ritual required. The crown is finished with a black spinel cabochon — a discreet, jewellery-like signature. Sapphire crystal
