How does the timer attach to the band?

you have to take the clip off, but it just slides right into the watch band and locks very nicely.

Description says "one size fits all" but there are 2 sizes offered. What are the measurements for the different sizes (small & large)? Thanks.

Never thought to measure and bought the smaller. It's adjustable, so while it does fit, I would say it's a bit tighter than I prefer so I bought the larger one. I don't think I have a particularly big wrist. Male, 5' 11" but no idea what my wrist size is.

Does this strap completely cover the back of the gym boss?

Yes the plastic mounting is the same size as the gym boss it clips on but you can still change the battery with it connected

I have a wrist size 7 inches. Which strap would you recommend since the small and large seem to be right around there?

I have a seven inch wrist and it fits fine.The strap measures nine inches in length. Since I purchased awhile ago, I think I purchased the large. I think you will be okay with the large. Also, the timer fits fine. However, at times it has a tendency to loosen. Make sure to it is tight prior to each use. I like the product. I hope it helps.
