For sale is an IWC 20 mm stainless steel buckle. This is intended for an Aquatimer but can work with any 20 mm strap. Please note the squared center pin! I purchased this for my Mark XVI and would have worked well had I had an appropriate strap. I ended up putting it on a nato so I have no use for this. Retails for $100 new on IWC's website, this is essentially BNWOB, however there is a small scratch on the underside of the buckle (you'd never see it when wearing it) but pricing it accordingly.
