To remove the bracelet on an Invicta Pro Diver 0590, locate the small pins that connect the links. Use a pin pusher tool or a small flathead screwdriver to gently push out the pins from the side. Once the pins are removed, you can detach the desired links to adjust the size of the bracelet. Finally, reinsert the pins securely to reassemble the bracelet.

You could make a friendship bracelet or ankle bracelet from small beads bought at any craft store and give it to your friend.
Don't understand what you mean by "secretly". The postal staff has to know about it. Anything small enough to be handled like letters can be posted anonymously though, as long as you have enough stamps on it.
