Service cost for a reverso with a 822/2 movement?

I am researching for a purchase and I always look at the future servicing cost as part of the factor. I know that the JLC website has a service estimator but I do not have the reference number as I do not possess the watch.

I think in the past the service cost for a basic manual wind was 450 Euros.

Does anyone know if that is still true today for the 822/2 manual wind?

Thanks.
