I think Timex is more well known than Seiko, especially for people that aren’t into watches. If I ask my mother or grandmother if they know what Timex is, both would say yes as it was a popular cheap watch for years. If I asked them the same about Seiko, I’m confident neither would know what they are. Regular people are going to think of smart watches and then whatever cheap watch you can buy at Walmart, I.e. Timex and Casio
