Although I might choose a Voutilainen Cal. 27 over the Dufour Simplicity becasue it would give me a rectanugular shaped watch to complement the RO, and becasue I have long loved the regulator time reading. Not sure about this one, but for all of the reasons you gave for the Simplicity, I might in the end choose that -- LOL, as if this is going to happen for me. I can understand how the Simplicity would spoil ou for all other watches.
I totally agree on the RO 15002. Perfect, iconic, enduring. When I first came across this post my initial response was that for the mainstream watch, I would have to choose a Jaeger LeCoultre because I cannot imagine being without one at this point. But there again, the 15002 has JLC as its heart and soul, so I guess that need would be covered.
So, now the question is, do I sell my other watches and work my way towards this simplified collection of two watches? I also agree with you about the desiree to also hve a sport steel or Ti watch, so maybe just three watches... ;-)
Best,
