... and certainly nice on leather.
Umm ... what's happening to the strap at the 6 o'clock lugs ?
Quick edit : Perhaps I'm seeing one of those sliding pin activated spring bars* where the strap has a split in it to access the pin thingee. I only became aware of those recently, a very clever way to keep strap tools away from the lugs on a nice watch (sensible too on a precious metal case with no lug holes). Thinking out loud here - perhaps I'm wrong .
* Dunno what the proper name is.
