I recently picked up a PF Kalpa which comes on a black gator strap. It was my first experience with a tonneau case, in fact my first experience with any case that's not round. I loved the feel of the watch on my wrist but felt the black gator lacked pizza...
The brown leather, of course that is a great match. But I admire your creativity with the color of the "summer strap"! The wrist shots are killer. Great call my friend!!
