I'll be going to a boutique soon, but I'm doing research beforehand. My wrist is 6" in circumference, so I'm stuck between being afraid the small will be too small and the medium will be too big
I have a small and I love it. I don’t think a medium would be a bad choice, but the band was wider than what I preferred when I tried them on, I liked the look of the small. I have a 6.25 inch wrist see what you think in person!
Yay, Cartier Tank club! I have the small Tank Francaise. The strap is 6 inches and pretty snug, although it can move over my wrist bone, so I guess my wrist size is about 5.75 inches (but I am not petite, 5'7").
There is no Cartier boutique in my state, so I never tried on the various sizes, and I also worried that the small would feel too small. But it's perfect for me! I love that it looks great casual or dressed up. I wear it every day, but also left it on when I went to the ballet, for example. The size is also very comfortable to me. Since the face is streamlined with the band, it never pokes into my hand when I bend my wrist, which happened a lot with my prior watch.
I'll just share every picture I happen to have saved on my computer.
For comparison here I am wearing a 30 mm David Yurman watch.
