It's funny, I just had this conversation yesterday with someone else. I've got several gens with 1030 movements and I never wear them anymore. Parts are too hard to find. But that look is inescapable.
So I built the Big Gonzo 6538 to replace the 6536 that rests now in the safe. I wanted something with the same strong vintage vibe, perhaps slightly different than the Small Crown, and something I can go swimming with. These are, after all, tool watches.
So I went nuts on expensive parts, and put a low-beat ETA movement inside. It's robust, parts are readily available, and if I flood it in the briny deep, who cares? The Big Gonzo is a tool watch too.
