Tommy Hilfiger TH1791455 Watch Parts Unavailable

Hello there, I bought your Tommy Hilfiger TH1791455 watch in 2019. Right now, I need 3 beans for it, but both the dealer and other sellers have let me know that the part is unavailable, and they can't help me. I picked out this watch because I had faith in the reputation and craftsmanship of the Tommy brand, but unfortunately, none of the sellers are willing to assist me, and there seems to be a lack of support for the product's components. Surprisingly, I didn't anticipate a well-known brand like Tommy to stop providing support for their products after only 4 years. Can you please help me with this?
