A Collected Man is mesmerised by the dark days, Northern Lights and the stunning monochrome look of the Icelandic winter. This strap, with its matte black yet smooth calfskin surface, reminds us of the island's jaw-dropping volcanic landscape.

Made exclusively in 21mm lug width with 16mm buckle, with a slim fit, it is made to fit contemporary Patek Philippe dress watches. Simple, understated, elegant.

Produced using a double-tanned calfskin, the Reykjavík is soaked in a mixture of oils to produce a soft and supple leather that fits comfortably from the first time it hits your wrist. This approach allows the strap to hold colour, and makes it less prone to fading over time.
