how to remove links from apple watch with link bracelet?

Do these "buttons" require the person to have nails? Can I simply press the button with a finger tip? Im having alot of difficulty removing these links. Im bending credit cards trying to depress these buttons.

open the strap at the clip.

look inside of the strap and there are "buttons" on each link.

press the button and carefully pull the link.

repeat to get required size

carefully put the two open ends together and press closed.

done

I see them as pulling apart and not sliding. My wife was able to do it but Im still having difficulties. Also read somewhere that the links or lugs get incrementally bigger as you move towards the watch. Is this true?

According to everything known about it you should be able to easily do it yourself.

I can push them with either the tip of my finger or the end of my nail.

I have absolutely no nails. Maybe Im trying too hard.

I have very little. You just need to depress it then slide the band.

Do you slide the band or pull the band apart?

Sorry wrong buttons, I assume they disconnect.

Slide - it's the same s removing the band from the watch
