He made his remarks several days after the firm denied working with Apple on a smartwatch project.
"Beginning in 2015, we will integrate fitness functions into Swatch Touch," Swatch Chief Executive Nick Hayek told Sunday's Neue Zuercher Zeitung am Sonntag, a Swiss weekly.
"It will remain a watch, but will have all today's usual functions to monitor physical fitness."
Swatch has in past rejected partnerships over smartwatches and voiced concern about being reliant on software and applications from other companies. Hayek told the newspaper the company would use its own electronic components to ramp up the Swatch brand Touch.
The Swatch Touch model is a touch-screen wristwatch launched in 2011 with a limited range of functions including time, alarm, chronograph, and date.
Like most Swiss luxury watchmakers Swatch has hesitated to jump on the bandwagon for wearables device with interactive functions.
A spokeswoman for Swatch was not immediately available for comment.
Swatch last week denied a media report saying it was working with technology company Apple on a smartwatch, a wearable device with interactive functions.
Technology website VentureBeat said in a report on Wednesday Apple was working with "at least one partner, Swatch" on a smartwatch project, citing an unnamed source.
A spokeswoman for Swatch Group said on Thursday the report was unfounded. She said the only business relationship Swatch Group had with mobile phone makers was as a supplier of integrated circuits and other electronic components.
