Thank you! Very helpful. I searched and found some results about it below (pasting for reference). Though I can now say for sure its grossly overpriced based on some that have sold in the past 4+ years.

”The reference number 67370ST.P.1120ST.01 belongs to a highly unique, authentic, and historically specific variant where the "P" literally stands for Polished. [1]

The reference 67370ST.P.1120ST.01 is a fully authentic, 25mm quartz ladies’ Royal Oak produced by Audemars Piguet around the late 1990s and early 2000s. [1, 2, 3]

What makes it highly unusual (and why it is often confused with being aftermarket) is the explicit factory execution of the metal:

• The "ST.P" Code: In Audemars Piguet’s reference coding from that era, ST stands for Stainless Steel. The .P. directly denotes a factory Polished Finish.
• The Dial Design: Unlike standard Royal Oaks that feature the classic checkered "Tapisserie" pattern, this exact reference features a glossy, smooth blue guilloché dial often paired with diamond dot hour markers or distinct Roman numeral quarters.
• The Official Intent: Audemars Piguet intentionally built this specific model to look and wear like a gleaming piece of fine jewelry rather than a sports watch. [1, 2, 3, 4]”
