Hi mfantini, welcome to the Forum.
I poked through one of the best references I've found here on Dynamics, but unfortunately it only details the mens' versions in detail. I'm more familiar with the first generation Dynamics that I've collected.

It looks like the smaller version of the 166.0146. You can see on the caseback it specifies Omega Tool 108 or an equivalent tool in order to remove the crystal and movement from the front. The reference will be printed inside the case.
FYI, an Omega Tool 211 unscrews the back ring for easy strap changes.
