Also cool that you have one of the watches on what I presume is the original IWC Velcro strap. As an aside, I wore a Tag Heuer Formula One on an aftermarket Velcro strap while I was a lifeguard and swim instructor many years ago and thought it a great alternative to the plastic strap that came with the watch... so where's all the Velcro gone these days?
Had I been smart (and rich, for a lifeguard anyway) I could have bought one of these instead of the Tag and had the Velcro included in the price ;-)
