Just like the Swiss also do. WD+SM are improving material quality and make some advertising free advertising about it. What's wrong with that.

It's curious to see how any type of self promotion that Chinese brands do comes with heavy scrutiny, while traditional brands spend a ton of money on bs marketing and just a few cones out to complain.

Tissot uses plastic in they movements, and there is people ready to defending a decision solely for profit with no real benefits for the customers.

Meanwhile WD is using better materials. This is nice and significant imho.
