Change strap/bracelet datejust 1601

Hi,

I would like to change the watch strap myself. Can someone recommend a spring tool do I need to carry the task? Does anyone know the size in mm for the lug drilled hole?

Thank you.

For sharing purpose.

I finally bought this spring tool and successfully changed the watch strap.
