The Longines isn’t an annual calendar. That’s a more sophisticated complication which only requires date correction between Feb - March.
This is month, day, date, moonphase, chronograph based on the Valjoux 7751, a common movement used by multiple swiss and German manufacturers.

I like the older version of Master Collection Moonphase Chrono. As others said, large discounts off of Longines MSRP are available from reputable sellers

Good chance you can get 20% off from an AD with Longines warranty.
Topper is a great AD, stand up folks whom I’ve dealt with multiple times before.
