So it should be 42mm. Still quite large, but not as bad as 44mm.
It's listed as a Senator Perpetual Calendar, Ceramic. It has the same hands as the rest of the Senator line, not the Navigator hands.
At least we can hope. . .
What I really hope is a typo is the case size of the Senator Chronometer. If it's 40mm, I'll have to get one. If it's 42mm as listed, I don't know.
That one is almost perfect otherwise. Please tell me the listed size is an error!
Although, with all the innovations present, I suspect the price will be supersized as well! 
Thanks for the report!
