I use a digital watch; at the moment, I have one that hangs down from the belt loop on a pair of jeans, but I have the same issue with wristwatches - buttons will accidentally get pressed as I move around, bend over, or do various exercises, and unintended things will happen (e.g., setting an alarm for 1:00 am).
How might I prevent these buttons from getting pressed accidentally? Ideally, I wouldn't prevent use of the buttons entirely, since I need them in order to, for instance, adjust for daylight savings time, but not of them need used terribly often.
I've searched for some sort of case that I could wrap around it, but haven't found anything. Some sort of DIY solution could do it (for example, covering the buttons with resin), but I'm not sure how I would go about it without permanently preventing access to the buttons.
