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.
My Trident Pro 600 GMT MkIII loses around 3 seconds over 9 days/nights continuous wear, only removed for showering. It keeps time in the same league as my Tudor Heritage Ranger and I'm very pleased with it. Unfortunately I am send it back to CW for service/repair as the GMT hand is misaligned - a common issue with the Sellita SW330-1 movement I understand. We'll see what the time keeping is like upon its return.

Sorry to hear that. I had that movement in a Mk2 Trident for a couple of years, and it wasn’t an issue for me, though a number of people did find it so.
I understand the 330-2 is much better in that respect, and I certainly haven’t seen the problem in my Sealander. It always lines up exactly.
I hope it is sorted for you. Are you within the 5-year movement warranty period? The model was introduced in May 2019.

Thank you. That is my understanding too re the 330-2 movement. I also understand that there is a series of updated parts that may be retrofitted to the 330-1 movement, the movement then stamped/engraved to record the change, that addresses this issue.
My watch is 01/22 so just over 2 years to run on warranty.
