A great gift idea for your mom who loves horology could be a beautiful and elegant wristwatch. You can find a watch that suits her personal style and preferences, as there are a wide range of brands and styles available.
If you are looking for something more unique, you could consider getting her a vintage or antique watch that has a special historical significance or a meaningful back-story. Alternatively, you could sign her up for a watch-making course or workshop, where she can learn more about the craft and techniques behind horology and make her own unique watch.
You can also consider getting her a coffee table book on the history of watchmaking or a subscription to a horology magazine to keep her informed of the latest developments in the field.
Or you can get her a star map with the date when she was born.
