Actually I quite like the RG 8 Day Perpetual Squelette. I thought long and hard abt. the Platinum version and still have my reservation: It looked/felt much smaller. (Perhaps I'm too used to my titanium MRM!) Moreover, somehow it's not exactly legible. W/ the contrast of RG and Ruthenium bridges on the 1833 RG version, I think it adds a bit of depth to the skeletonized movement. I'll be looking forward to seeing this piece in real life.
Did you have a chance to listen to the RG Master Repetition Minutes? I wonder how it sounds compared to the Titanium version.
