Apple Watch Cases

Apple Watch cases, by case size and series.

Apple Watch cases are sized in millimetres, not by series name, and the size is printed on the back of the watch. Find your size first, then choose protection.

How to choose

• 100M Waterproof — A full seal with a fitted band. Rated to 100 metres for swimming and diving.
• Waterproof Sport — The same seal with a sport band for training rather than depth.
• Rugged — Impact and scratch protection without the full water seal. The everyday option.

Covers 38mm, 40mm, 41mm, 42mm, 44mm and 45mm. Waterproof models ship with a band; rugged models are case-only unless the product page says otherwise.
