Chronoswiss, which is best-known for its regulator-style watches, has been selling online since 2015. This is a relatively long time within the watch world, despite being much more recent when you think of it in the broader e-commerce context. I ran through the check-out process at the brand's online shop and paying with Bitcoin is just as easy as paying with any other method. It's just another menu option. Chronoswiss is using CoinGate to calculate daily exchange rates (from US Dollars or Swiss Francs to Bitcoin) too, so trying to speculate too much would be rather difficult.
