Tell her to get the MK if she likes it
That MK is a big watch even for a man at 43mm, does she want a big watch like that or that's just something she didn't think about.
Here are some smaller but similar watches in design.
Citizen FE7053-51X
Citizen FD2013-50A
You could browse here for something else in you are in the US. These are less expensive and better watches. Just don't hide it in a drawer in the dark when not wearing it so it can get some daylight and it'll just work for many years since it's solar.
If she actually wants something bigger, just browse the men's watches on the same store maybe there is something in roze gold.
If she can find something she likes citizen eco-drives are much better watches than MK. Something from Casio's Sheen line would also be a better choice when it comes to quality and durability but it's what she likes that's more important probably. Also a chronograph it's not the best choose unless she will actually use it to time things,if a watch is more complex there are more things that could go wrong with it.
