There are a few things that I note, trying to be objective.
1. OP bought a modified 7750 decorated, not a 4401 clone, knowingly as he has the links.
2. The watch was returned without stickers. You don’t need to remove the bracelet stickers to see the dial
3. OP has no history of TD reviews for the claimed prior purchase
The golden standard here is that the buyer should know the limitations of the exact model that he is buying. The TD is here to sell the exact watch ordered. They are not consultants.
It’s beyond naive to expect that they can be versed in the thousands of models they sell.
OP ordered a specific watch and provided a link. The exact model was shipped. The story should have ended here.
InTime accepted a return, that shows good faith. They could legitimately have refused but they did accept. If all the stickers were on, then that would have been a different story.
OP, do you have irrefutable proof that you sent the watch back with the bracelet fully stickered?
I appreciate you trying to be objective. Since you've put in the time to write this, I feel inclined to share my side of things:
1. Whether its a modified 7750 decorated or not a 4401 clone, I don't really care or understand. I really like the model I saw in the video of the provided link, where you can see that all the chrono parts move and once the reset button is pushed, all the chrono arrows point to 12, being reset also. You can see in my video that this isn't the case with the watch I got. So clearly this "modified 7750 decorated" watch was faulty and needed repair.
2. I have returned a number of watches to TDs for repair without any stickers, but using the same method as here- I put the silicone protector on the dial and wrapped it tightly with bubble wrap, putting it in the box. My watch never came back as beat up and scratched as what was shown by our super trustworthy TD Ryan from InTimeWatch. So I know for a fact that I didn't scratch that watch and I wouldn't be scratched in transit. So it could only be scratched by Ryan himself or the people in the factory who tried to repair it.
3. I don't have time to praise TDs like TrustyTime or PureTime on this forum (or any other) for how often they update their website with new watches and especially Trusty for even providing many videos of watches they sell. I am a big watch lover so I check their sites a few times a week for years waiting for the AP to finally get a gen chrono into a smaller case which it seems that they finally managed to do. I run a business myself selling physical and digital products and know that a bad review is never good for a business. And we process returns on weekly basis and never it came to my mind that I can just damage my own product and claim it was buyers fault so they will not get repair or return. I can write any BS in my terms and conditions claiming that I need restocking fees and that refunds are never possible, but at the end of that day my priority is to make my clients if not happy but at least satisfied. And that is far from InTimeWatch's is doing.
4. To address the remainder of your post you can go to point 1, where they shipped the exact watch as per my link, being:
https://trustytime88.io/index.php?main_page=product_info&cPath=352&products_id=28409, take a look at how the chrono works in the video and compare with how the chrono works in the watch I received and took a video of:
https://we.tl/t-ZiHZTqamJp. InTimeWatch accepted a return, not in "good faith" but because they fked up twice: they didn't understand what they were selling and what they sold didn't even properly work so they tried to fix it. I think they couldn't fix it so all they could to was to scratch it up and tell me to fk off, because they knew that their reputation is strong in the community but if I put a small dent in it, I am already super happy.
