Easy to adjust a slow IWC Mark XVI?

[DC1971]

I just received a Mark XVI from one of the TD this week and the watch is running about 10 secs slow per hour. Is it a straightforward thing to open up the caseback and adjust it by trial and error? I don't need the watch to be running perfectly on time but losing 10 secs per hour adds up to quite alot. The XVI i have is the one that has the Asian 2892 movement. Any help is appreciated. Thanks in advance.

You would need a vibrio graph or similar as it sounds like the beat will be well out as well if it is 4 min slow a day

thanks for the reply. I have contacted someone to do a complete overhaul for me. Rather irritating as the QC pics showed all the timegrapher results to be 'great'.

Who did you contact? My 4 mo. old Mark XVI rep just died. I need to have it fixed.

Who to try and contact really depends on where you are located. You should be able to get suggestions if you specify your location (US, etc). Or do a search like 'watch repair US'. I'm based in asia.
