43mm you say? That's a proper man-sized watch for something that is so delicate in aspect.
I don't mind the date window at all so long as the date disk is tone-on-tone as you (and others?) have remarked. It is however the absolute ruin of watches where there is a high contrast between the two.
I have a 38mm cousin dating from 1997, just back from servicing. I posted about this some time last year just after I joined this forum. I call it the 'São Gabriel' for reasons of its origin. The Portuguese jeweller/designer J. Borges Freitas has the first of 750 in their keep.
