Recommendation for Autavia service/repair in/near Kent/Lon

[Cheburator mk2]

As per the title,

I am looking for recommendations for a place to have my Tag Autavia serviced and repaired. It has been sitting in a box for the last 7yrs, missing a chronograph pusher button and looking very sorry for itself. I would like to start wearing it again, so it needs doing. I loathe to go down the route of an official Tag service center - thus any independent recommendations would be great.

Thanks in advance

I'm also looking to get my Carrera serviced. Just loathed to send it to Tag and pay £250+ for the privilege.
