I found one locally a few years ago in a desirable configuration (218-9 chronometer movement, silver and black dial, steel case), but there was evidence of rotor wear, plus an extra set of springbar holes drilled into the lugs, so no go. A year later, mrsnak and I discovered this gorgeous UG that shares design cues with the Polerouter . . .
