what do you mean by "fashion " watch like they dont last long and are more for looks rather than actual function?

I didn't write "fashion". I wrote "lifestyle brand". That is what they are: they have a variety of accessories to meet the style of a particular market.

like they dont last long and are more for looks rather than actual function?

They are made for looks, but they use quality movements as far as I see. Their prices are high for what you get relative to watch manufacturers.

For the money, you can indeed get better watches from other brands like Citizen and Casio and Seiko (and their associated brands).

It was used the seller clamied " excellent condition " and " new battery "

Contact the seller. It is easy for amateurs or careless people to cause problems installing batteries, and the claim simply might not be true.
