My other previous VC all ran within 2 sec/day. They refused to do it as their official certification allows for ~8 sec/day. I was so furious that I decided to sell it on the used market (I did not make money on this - even lost a bit). What bothered me is the lack of customer service to regulated it a bit better which they clear can do. My Cartier Tank was running 8 sec/day and my dealer got his watchmaker to regulate it for me to 2 sec/day! I could have tried to have my Oversea regulated in a non VC service place but at that point I had mentally disconnected from the brand sadly.
