So, my mom took a close look at my MM300, and I geeked out about the monocoque case, and the clever helium escape mechanism, and the ratcheting clasp, and she really liked it. Of course, my petite mother doesn't have the wrist to pull off the MM300's size, but she would like a watch like it.

Any ideas? I would think less than 37mm or so, but no smaller than 34mm. I'd prefer it to be Seiko, but I'm open. Price doesn't really matter.
