The inscription may be to herself, but it's clear that Markle dreams of passing the watch along to a daughter. Perhaps we're getting hints of an intended name? Or perhaps it's intended as a wonderful reminder to treat oneself well and to know one's worth — values that have served Meghan well both in her career as an actor, and in her interactions with the royal family.

Either way, the engraving makes a piece more personal, and it's obvious that Meghan values a personal connection to jewelry. When playing Rachel Zane on Suits, Markle was known for wearing her own jewelry on set. As she told Marie Claire, "All the jewelry that I wear on the show is my own personal jewelry and family heirlooms, like my grandma's charm bracelet and my signet ring." The ring, which bears an "R" for Rachel, Meghan's first name in real life as well as that of her Suits character, was especially appropriate and a stealthy way to add a personal touch to her wardrobe.

Whether their future daughter will have an "M" or an "R" in her initials remains to be seen, but one thing is for sure: Meghan and Harry can't wait to welcome her into the world.
