The company, most known for its brightly coloured plastic-cased watches and which in recent years has accustomed investors to double-digit growth, reported that net profit rose by 6.1 percent to 768 million francs ($820 million) for the first half of the year, compared to the same period in 2012.
Swatch Group sales, meanwhile, moved 8.7 percent higher at 4.1 billion francs, the company said in its earnings statement.
The watchmaker said that it was the victim of its own success last year, with growth appearing weak compared to "the very strong first half year 2012."
The net profit was slightly higher than the 733 million francs expected by analysts polled by the AWP financial agency, while the sales were in line with expectations.
In recent years, the Biel-based group has seen its business balloon thanks to a seemingly insatiable appetite by Chinese consumers for luxury watches.
But company chief Nick Hayek warned in March that the massive growth could not go on forever.
Over the last six months, Swiss watch exports to China have slowed, in part owing to a recent ban on ads for extravagant gifts in an anti-corruption push.
Earlier this month, the French luxury products group Hermes reported signs of a slowing of demand in China for its watches.
Swatch nonetheless said the outlook for the remainder of the year remained "very promising," saying that "a strong second half-year is expected."
While Swatch's low-end plastic watches are perhaps its most recognizable, the Swiss company operates in every price range, from the Flik Flak children's watches to prestigious timepieces under, for instance, the Breguet brand, which can cost more than one million francs each.
The watchmaker said on Tuesday that it aimed to launch a number of new products in coming months and that it would continue to work to integrate recently purchased US jeweller and watchmaker Harry Winston.
Following the announcement, the price of shares in Swatch Group rose by 1.89 percent to 539.50 francs in early trading, well ahead of the Swiss stock exchange's main index, which dipped 0.2 percent.
