Hi rcv3
Welcome to the Apple Community.
Sorry I don't know the size in mm for a size 9 band ... wondering if the band is an Apple one .
(Perhaps you could lay the band out flat and measure it carefully to get a precise mm.)
Hoping the information below on current sizes may be helpful.
Online: Buy Apple Watch Bands - Apple
with some styles:
S/M band fits 130mm to 180mm wrists
M/L band fits 145mm to 220mm wrists
Eg: For Green Alpine: 49mm Green Alpine Loop - Small - Apple
says:
"The Trail Loop, Alpine Loop, and Ocean Band are designed for Apple Watch Ultra
and pair best with the 49mm case size. The bands are also compatible with 44mm and 45mm cases".
Small fits 130 to 160 mm wrists

For optimal performance, your Apple Watch should fit closely on your wrist.
For best results, the back of your Apple Watch needs skin contact for features like wrist detection, haptic notifications, and the heart rate sensor.
Wearing your Apple Watch with the right fit—not too tight, not too loose, and with room for your skin to breathe—keeps you comfortable and lets the sensors do their job. In addition, the sensors work only when you wear your Apple Watch on the top of your wrist."
All the best :-)
