Its everything I thought it would be - I have been coveting this piece for several years. Previously owned an RM010, which was awesome, that I then traded up to an RM011, which I was not happy with because of the jumping hands situation caused by the modular movement. I knew the 004 was the top of the heap for me but never had a realistic opportunity to purchase one until recently.
I have to admit that it took some reflecting and soul searching before pulling the trigger especially in light of the recent posting by gls and some of the other anecdotes I heard of some pieces having some quirks with the split second function (as evidenced in Richard's own post from last month). This particular watch has been working flawlessly, and in any case I don't intend to play with the split function all day long.
In addition, I figure that if there are in fact further design changes, I will send it in and it will come back like a new one (granted it could take some time ..). My hope of course is that the watch will continue to work perfectly and I could determine when to send it in for service on my own schedule, or maybe never ..
So I am currently very happy with it and just astounded at the depth of the dial, the intricacies of the spectacular movement, and just the sheer uniqueness of the RM pieces. There truly is nothing else like them out there and I can't get enough of them. For me personally they embody all the things I love: cutting edge design and look, mechanical wizardry, high end technology, and motorsports themes. As a comparable, I had a PP5970 a couple years ago but it only lasted a brief period of time - even though it is a 'grail' watch for many and is beautifully finished, it just did not say anything to me when I wore it. I had convinced myself that it would be the ultimate for me because of all the hype. The lesson I learned that time is that you have to listen to your heart rather than your head when it comes to watches ...
