It looks like that plant is having multiple problems.

What does the newer foliage on the plant look like right now? The reason I ask is because the brown rings looks a lot like damage from a virus, but that should also show up on foliage.

But it also looks like those fruits have quite a bit of pest damage, including stink bug damage, and it's possible the marks are from some kind of mold or fungus that found a way in through the pest damage.

Agree that it looks like TSWV on the fruit but I don't see any of the usual symptoms (stunted leaves turning yellow or with yellow speckling and dark streaks ) on the plant in the photo except maybe 1 leaf.

TSWV

So if the plants appear healthy then the odds are the fruit damage is from some sort of pest.

Folliage is showing no symptoms at all. From a distance, this plant looks like it's thriving - it's about 8 feet tall at this point.

I guess i'll pull all the affected fruit and wait. The only real pest problems I've had are earwigs but I don't think they can be responsible for this.

I would bet you have more problems than earwigs but that it's hard to see the pests.

In my (very limited) experience...usually some type of tiny worm goes in circles like that...I think it's larvae from something that has recently hatched? Look on the backside of the leaves, too.

I see in the picture couple of spots eaten by something. The marking might be due to some chemical etching fro the insect crawling on the tomatoes.

I think those nibbles are from a groundhog? I had to relocate one who did a bunch of damage to my nearby kale. I removed about 8 tomatoes with similar symptoms and the rest seem to be growing fine. There are probably 20 fruit on the plant which look healthy, hopefully some start to pink up soon... I have yet to receive a ripe non-cherry tomato yet this season.

The season has been great so far though, I can't complain... only started gardening last year and I've learned everything I know from these forums. I haven't had to purchase a vegetable since the start of May and frozen a bunch for the winter as well! Maybe i'll post some picture of my healthier plants, it's quite the jungle.

To be fair, I do have a few pest issues but they haven't really touched my tomatoes or peppers. I've had leaf miner on my beets and swiss chard, cabbage worms on some of my greens (treated with BT) and the cucumber beetles have made a home on my squash and cucumber plants.

I spotted some Japanese beetles the other day so I'm sure they will come in with a vengeance soon.
