congrats regarding your new acquisition. I find the Octo Roma a very interesting, more robust alternative to the Octo Finissimo.
It looks fantastic on your wrist.
I am one of the watch lovers you mentioned who have a problem with white date windows not matching the dial. ☺️
BUT - as you wrote - here the design was made perfectly. The date window in addition to the shorter index on the right side is in perfect balance and harmony to the left marker. I like it!
I have no problem with the 41mm case size. But you are right: maybe 39 or 40mm would be an interesting alternative. 38mm would be too small for my very personal taste.
All the best and wear this beauty with joy!
