I just got a 22mm pilot strap in cognac vintage colour with the brushed PRE-V buckle from Steinhart, and put it on my IWC BP and just want to say what a nice strap it is.I have a hard time finding straps for my 8 1/4" wrist and got the 160/90 and it fits perfectly. buckle goes in the middle hole and strap is 5mm thick. Nice and plyable and a great colour and the buckle is nice and thick at 3.5mm. Fast shipping also from Germany to Australia in 5 days. I will be ordering a couple more.
