Sorry about the huge pic of my DavidSen Pam 195 amd MMX strap... but look closely... you can see the buckle emerging from the shadows. Not too clearly, it is a stealth PVD buckle
But of course, if the strap was the right size for me - you would not be able to see the buckle in this pic... it should be opposite the watch, not creeping around my wrist.
So, no worries, mate. An MMX strap will fit your wrist better than it does mine.
Failing that, you can use it around your waist, to hold your stubbies up, cobber
Exit Clive, singing, "Tie me Panerai down, sport, tie me Panerai down..."
Bonzer timekeeping!
