Bracelet + Case sizing

Hello everyone, I am trying to buy a bracelet for my Omega Seamaster 300 14755. I found one that is 16cm laying flat, can someone tell me if that would be ok for a 7.5" wrist? My answer is yes based on my crude calculation: 3.9cm (39mm) of the case + 16cm of the bracelet equaling 19.9cm, which would come to 7.83". Am I missing anything?

Thank you
