Hey everyone, iwc_ian here. Found this absolute beast of a watch at an estate sale and I'm trying to pin down exactly what it is. It's got that classic big pilot DNA - we're talking 46mm+ case, black dial, Arabic numerals, and a seriously thick presence on the wrist. The crown is massive and the lume is this gorgeous cream color. I'm pretty sure it's IWC, possibly a Big Pilot from that era, but I want to make sure before I get it serviced. Anyone recognize this thing? I can post more photos if that helps.
