Tons of them. If you have a specific model that you're wondering about, please ask.
Typically the sandwich dials are found in the newer models. The older PAM111 had sausage dials while the newer iterations it has a sandwich dial, for example.
Here's a short list off the top of my head of some (assumes it is the current/most recent version of the watch):
127
217
183
210
231
111
177
112
176
219
198
200
232
233
EDIT -- Copied this from the other sandwich dial thread. I have to admit, not all of those were off the top of my head, I had to hit up panerai.com for some of the more obscure ones. :wink:
