Robb Report/Everywatch says 36mm Day-Dates are up 57%?

This article was mentioned in passing in another thread, but I’m wondering about both the underlying data and what current buyers are seeing.

The article cites Everywatch data claiming that 36mm DD values rose 57% just in August 2024. Considering there are almost 70 years of 36mm DDs, and a near-infinite range of conditions, dials, bracelets, accessories, etc., it seems awfully tough to come up with any meaningful figure. My first instinct is to suspect an inappropriately small sample size, but they claim otherwise.

Note that Chronopulse data (from C24) says 36mm DDs are down 12.73% over the last three months (although that may be measuring only 18238s, it’s not clear).

What’s the impression of people who have been shopping in the secondary market for a DD36 over the last few months? Has anyone dug into the Everywatch data to see how they reached their number? If that 57% number is anywhere close to accurate, what’s driving it? Is it really reflecting DD values, or just the values of a few rarer dials? (I’d also expect the percentage numbers are not uniform among 4-, 5-, and 6-digit DDs.)
