Calibre de Cartier movements and mods

[lolz123]

I've been looking at the calibre de cartier for the longest time and came across

 

http://www.ttw888.com/index.php?main_page=product_info&cPath=21_335&products_id=9078

 

and it says modded with subdial at 6. How bad is this mod? is it a time bomb like the daytonas?

but this isnt an a7750 mod but a 2836 mod.

 

I came across an old thread saying that this mod isnt that harmful. But i know with all mods, they could be iffy.

 

Can anyone provide input?

 

Thanks,

Anyone? I'm wondering the same.
