Welcome to the forum! 40mm-44mm is most likely the case size measured across the case(may or not include crown) If you have smaller wrists the lug to lug size may be more important. Some watches of similar dimensions "wear" better than others. There may be a thread on members with smaller wrists and the watches they wear. Remember "search" is your friend. Good luck!
Here is one from another rep forum. https://www.google.com/url?q=http://...wbqxpVZVmqjGJA
