The current Apple Watch SE uses a nylon-composite material on its back side.
Apple is reported to have tested replacing the metal portion of the current Apple Watch SE case with rigid plastic to lower the cost.
The current SE model adopted a redesigned back case that changed to a color-matched “nylon composite” plastic material in 2022. If true, this report would see the entire chassis of the Apple Watch SE changed — making the device less environmentally friendly.
