Resurrection to add another idea. I put this watch on (cold start, no winding, power up on the wrist) on Monday, and after 72 hours…

When I took it to Malta in April it gained 22s over 8 days. Still very good. It goes to show that even these very precise/accurate chronometers are subject to slight variations depending on external conditions/positions/state if wind &c.
I wish my Twelve Ti performed that well. It's now running well out of COSC specification and losing 7-8 seconds per day on average.

You wrote 'now running', implying that it was different before.
Mine is +1.5s/day. My Sealander Elite is running about +1s/day.

It ran well within COSC specifications for the first few months but gradually deteriorated until it settled down at the current rate.
Would CW regulate it back to the correct specs under warranty?

I think you would need to contact them. Send them that photo. It demonstrates that the movement is not conforming to specs and not running within intolerances.
