I recently purchased the above watch and want to put it on a rubber strap, can anyone help with the size “prongs” I need on Spring Bar Pliers to enable me to remove the leather strap?

Also any recommendations as to which pliers to purchase?

Thanks in advance.

 

Please do yourself a favor and take your watch to a watchmaker and have them change the strap.

 

And maybe ask them to show you how it’s done for future reference
