TAG Heuer’s smartwatch provides a versatile platform, although cycling specific functionality is limited

The market for smartwatches is growing, so it makes sense for a prestige watch brand to get in on the act. With its sporty image, it’s a natural arena for the Swiss brand and the TAG Heuer Connected Modular provides a flexible entrant into the field.

TAG Heuer has been a sponsor of the BMC Racing team for a couple of years now and the Connected Modular offers functionality of use to the cyclist. It’s worn by BMC’s riders – at least before and after races, and Greg Van Avermaet could be seen wearing a yellow strapped model to match his jersey at the Tour de France.
