Watch band
The PineTime uses a standard 20mm watch band / strap. There is a thread in the forum discussing this.
Due to the watches design. Retention for the spring bars are recessed into the watch. Not all 20mm bands / straps work. This is especially the case for Nato style bands / straps being too thick.
Known working bands:
BISONSTRAP 20mm Quick Release Silicone Watch Band / Amazon US
DMVEIMAL 20mm Quick Release Watch Band Metal Strap / Amazon US
Morsey 20mm Quick Release Watch Band / Amazon US
