Leather strap size doubt
 

Hi guys
I have to buy online a tan leather strap for my Panerai 111 44 mm and I don't understand the size I have to ask for. For example I saw this add: 100% authentic Panerai OEM Brown Calf Strap 44MM 115/95 24/22'
This is good? The 111 comes with buckle not with deployant.
Thanks.
