Need some help on a gift for my mother's 60th birthday

[singe89]

My mom is tuning 60 and I'm looking at getting her an AP.

Let me start with a little background. My mom is the hardest working person I've ever met in my life. My parents got divorced when I was 2 and my mom raised me. We lived in a 1 bedroom apartment for years while she worked full days and got her college degrees at night. She earned her bachelors and masters and now manages the OC office for one of the top 10 law firms in the US. My mother and father ended up getting remarried when I was 12 and they had two more kids. My father was a firefighter that passed away on duty 5 years ago and my mom still fully supports both of my brothers. She also watches both of my young kids when my wife needs a break (1-2x per week) even though my mom still works 50+ hours a week. I want to get her a gift for her 60th that she will enjoy for many years to come and she would never get herself.

I'm thinking of getting her a Lady Royal Oak in rose gold with diamond bezel or the new rose gold lady millenary. What would you suggest? She wears a Rolex lady datejust with diamond dial that I got her years ago as her daily watch. This would be more of a special occasion piece. Thank you for your feedback!
