How much does servicing cost and how long does it take?

[Mistry]

Hi all,

I have an OP that is worn a few times a month.

It is past its 5 years since purchase and so I was wondering

how much it costs for servicing these days and how long it takes?

I can do it in London or Switzerland
Since I live in London but work in Switzerland.

Since there have been price increases and all, I am guessing the servicing costs have changed also.

Thanks all!
