TC COSC Card - How do I read it?

[vegasbaby]

Included with my TC LV was this card:

Beautiful stock and embossing, btw...clearly nothing this man does is ordinary!

Anywho, can someone tell me what these numbers mean:

Searches on this forum and Google aren't returning much...and what is returned is not easily interpreted my a layman like myself.

Wow that is a pretty watch my friend, congrats.. Sorry can't help with the time variances.

 

[QueTip]

Should be the variations of how much the watch loses or gains time.

Left side where it says CHmax it's the starting time when fully wound. And last after 9 hours being fully wound.
Right one when wound minimally and the same thing.
Not 100% sure but I think that is the explanation for it. (98%)

Thanks, this makes sense...

First line CH is explaining how the watch was performing face down , it varies from +6 to + 0
Next line is face up
Next marker 3hour which is crown up
And so on
In real life in exception of Rolex SA nobody do the test in 24 hours, that could be done in 15min
According to his chart, your watch is keeping COSC standards as max deviation is 8sec/24h

Wow TC goes the extra mile. The little things like that is what makes a difference. Glad I got my hand on a TC dial and DWO to swap into my current YM.

Yes! You have a very good movement in that watch. TC marked my last one with "Almost COSC" as one of the numbers was 11. Just one... the rest were very low numbers.

That is absolutely beautiful and very accurate, wear this in good health.
Mine is in the queue, anxiously awaiting it's arrival.

Heh. Awkward...

 

[flieger123]

When did he start adding this? What a legend.

 

[SUMIKITO]

Oh yes, TC is always a few steps ahead of everyone else......he sets the pace and the 'standard' for everyone to follow !!

If Jesus came to earth today, he'd probably be wearing a TC yachtmaster.

Lol. Whoops
