Because I'm not a big fan of colored gold watches, but I've seen it in RG and Yes, I agree, this is a different watch.
The cold timeless look of the SS turns in a warm and very appealing watch, and yes, on the Reverso, the colored gold works very nicely.
As for the Grande Date, in SS or in YG or RG, this is a super watch.
Some may not appreciate the relative thickness of this watch, but it is really a matter of taste.
The dial is sober, classic, timeless, and the movement is great, with its 8 Days power reserve, and this lovely grande date.
A winner in my book.
Best,
Nicolas
