I have just purchased Apple's official Saddle Brown Classic Buckle leather strap. I prefer their appearance over any other Apple Watch band, but on the other hand I also do sports (gym, biking, running) everyday and feel like switching to sports bands and back every day will be too much stress.
My question Does anyone have long experience in doing regular sports with the leather belt? My concern is that sweat can damage the leather and carry it out. I can take the shower off, it's not a problem.
I also sleep with Apple Watch to track sleep quality, and the leather strap is probably not the most comfortable to sleep with, but it's something I can test myself.
