It depends on where you're located...Here, in France, for a Vintage piece, it can take from 6 to 12 months, but your watch is not a Vintage...
For a modern watch as yours, it takes normally something like 6 to 12 weeks for JLC to service a watch...
Things are different for any brands...
For example, Panerai need an average of 8 months to service in Swizerland a pre v, while it takes 6 or 8 weeks when the service is done in France for a vendome watch...
As for Breguet, it took 4 months to service a moedrn watch, while for other guyus, it has been longer, or shorter...
Etc...It depe,ndsof a lot of things, but I can tell you that 22 months is not normal... It looks a bit too long for me.
Another thing, and here this is normal, a mechanical watch need to be serviced each 5 years...Yoiurs needed this service, obviously..
Let meadd that your Master Géographique is a splendid watch, indeed...The funny thing here is that it has been this watch that make me do the plunge in the JLC world!
Best!
