Most watch faces are round, so a sphere seems like an obvious place to store one. The Chronosphere from AIS Collective can oblige. The outer shell is Tide Ocean material, made from sustainably sourced and repurposed ocean PET, while the interior is lined in Chamel Recycled, a suede-like fabric that keeps scratches at bay, while also being made from 84% PET. Designed by Maximilian Maertens, known for his work with MB&F and L'Epée 1839, it's a functional work of art.
