Apple Watch Sport Loop (Ultramarine, 46 mm, Fall 2024)

The Apple Watch Sport Loop band was woven from nylon thread to create a hook-and-loop closure. These bands were available for the 42 mm and 46 mm Apple Watch models (2024), and were offered in sizes to fit 130–200 mm wrists (38, 40, 41, 42 mm) and 145–220 mm wrists (42, 44, 46, 49 mm).

Beginning with the Apple Watch 10 iteration, the 42 mm description became arguably more confusing, as the larger model of the original Apple Watch (Series 0 and 1) was described as “42 mm,” and now the smaller model of the current Apple Watch (Series 10) is described as “42 mm.”

Beginning in Fall 2024, Apple began offering bands in the monotone colors—a design concept first available nearly 10 years ago with the original Apple Watch. This “Ultramarine” color is a shade of blue with a hint of violet. The connector and closure plastics also matched the Ultramarine color of the band (as opposed to using contrasting colors for the plastics).

Apple also began describing this band as “Carbon Neutral” and including a description of the environmental benefits along with the general product description:

“Soft, breathable, and lightweight, the Sport Loop features a hook-and-loop fastener for quick and easy adjustment. The double-layer nylon weave has dense loops on the skin side that provide soft cushioning while allowing moisture to escape. This weave is made with 82% recycled yarns, some of which contain material from discarded fishing nets. This band is carbon neutral. The Sport Loop contains 45% recycled content by weight, 100% of manufacturing electricity is covered by clean energy, and 50% or more of all carbon neutral Apple Watch products are shipped without airplanes.”
