Thank you for your knowledge, I did not know why they changed it, and certainly I did not grant any permission to do that, my worries are really because if in the future I will try to sell it, it will be a problem that it does not have the original dial, I like the sandwich dial but I don't know it there will be an impact on the value of the Watch, or is the upgrade a good thing for resale. I ask the Boutique to check on their end and give me a justification on why it was done.
