when it comes to annual calenders. Patek defined annual calenders, my first love was the 5035 onwards....i prefer the classical designed dial of the 5146, over the window display 5396. the Saxonia relative to other makes will be great, but not to Patek's annual calenders, IHMO.

The new Glashutte Senator Perpetual Calendar in RG offers much more....
PC function in a much cleaner dial / readable layout.
At a lower price as well....
