Sub or Yacht for Late 30's Woman...

[5nit]

My GF is now, because of me, a watch lover. She loves the idea of a Sub on rubber for herself. She's sporty so this fits her style.

My plan next year is an engagement ring and a new watch engraved. The Yacht 40mm blue face has caught my eye though.

Any thoughts on the Yacht vs. the sub for a woman? Any women on here that wear a Yacht or sub to chime in??

Thanks team. As these watches are difficult to get I need to plan well in advance.
