readability to add a pointer calendar (with an additional hand) instead of the date window at 1:30?
The "sunken" date window is something i do not love very much; same with the Vintage45 with power reserve (ref. 25850):

For the Vintage line i personally could imagine a pointer calendar could work nicely (besides emphasizing the retro-look):

Thank you for sharing your thoughts!
