The 99.1-M is the medium 40 mm size. The 99.2-M and 99.6-M weren't out when I got the price list, so that's why they're not there. For a feel of how much extra the medium case is I'd just see the price difference between 99.1 and 99.1-M.Thank you, Tangomat and En-Nissen! These price lists are hugely helpful!
There are a couple of things I can't find on the list, though--is it possible to get a medium case (40mm), and how do you get the price for the particular dials?
I'm probably not reading the list right....
If you ask them, I'm sure they can do most models in 40mm size.
