I have had a problem with the watch!! When I have set the date, the numbers have been grated below the dial. Now, they are disappearing and there are small residues in the dial. I think that the last revision had not been made correctly. I wrote to seller because the watch has a year of guarantee. I don't know if this problem will be difficult to resolve, because I think will be necessary change the date wheel. What do you think about? Thank you
