Tool for changing strap / bracelet

[benlee]

Hello. I will like to learn how to change straps / bracelets on my watches, not just Rolex but other watches as well.

In another forum, someone recommend me to purchase this tool



Will that be sufficient or I also need other tools? Thanks in advance.

I watch some youtube videos about strap / bracelet changing and the guys seems to be able to take off the bracelet so easily, literally in seconds even with just a blade. I have tried to take off the bracelet of my Pelagos with a small screw driver but it won't even bulge one bit.
