I've owned various classic Moonwatches over several generations over the past 25 years, and a few days ago added the white dial to my black 3861 Hesalite. I love the white dial, which just has bit more of a luxury feel to it with the gloss dial and sapphire crystal. The black dial is just classic, and looks far more like the instrument that it was designed to be. Personally, if I had to keep one, it would have to be the black dial. The character of the watches is different enough that owning both doesn't feel like having a duplicate in the collection. In terms of cost, owning both is roughly what a single current-issue stainless Rolex professional model is trading for in the secondary market.
