I wasn’t at all convinced until I tried it on the wrist, all I can say is I’m very happy. Instantaneous day/date is a great new complication and the change from round to baguette diamond to denote platinum is a nice touch. I feel the strap version possibly wears slightly smaller than the bracelet versions despite the extra thickness and hence my choice.
I should add, I had the chance to handle the full current collection at the same time as looking at the Cubitus. Particularly I was able to compare it to the 5980G which I had on order, after the comparison I changed my order and picked up the Cubitus instead.
