What exactly do you see that looks discordant or troubling to you? We’re comparing two fairly low resolution images, granted, but the movements seem identical to my eye, and equally well finished. The weird gold hue on the rotor is just a reflection, and in keeping with the generally poor quality of the image.
If anything troubled me it would be the collar or movement spacer ring (is there a better name for this part?) – the outermost ring that secures the movement in the case. It does not look to be finished at the same level as the movement, and certainly doesn’t compare to the ring in the first photo. But this might be because the same movement is being shown cased in two different models.
The seal of the case also looks pretty degraded, but I don’t know anything about the age of the watch – or if it’s being sold as “recently serviced”. If so, a seal in this condition might beg to differ with that claim.
As always, buy the seller and go with your gut. An honest and reputable seller will never bristle or break off a deal after being asked for a higher resolution photo. But if you have other reasons to distrust the seller, and it sounds like you might, cut your losses and don’t go forward.
“Buy the seller” is so widely used around here it has become a cliche, ...but it’s a really useful one.
