1815 Chronograph black dial is the bee's knees.
I prefer it over the Boutique edition though it is no slouch. It’s personal preference.
Either one beats the pants off of the other two IMO. Either of the 3 will have not so great value retention if you buy at retail, so pick which one really speaks to you. If you buy right, the value retention on the Lange is not so bad, but if you truly love the watch like I do, any worry about losing money on resale will melt away quickly as I have not thought for a moment about reselling.
