Most of us go through these phases, being super careful with you Panerai, It has been 3 1/2 years for me now and still my watches go on the polishing cloth when I take them off, the one I do not use, carefully packed.
You mentioned that at one point your watch stopped running accurate, how long did you have the watch and how did it come back?
Looking at the wrist of your lady, maybe a 42 or 40 would fit her better or you must have a second plan where the both of you can share both watches!
Have a great day!
