The Watches of Switzerland Group said trading has remained strong through the cost of living crisis as it takes an even bigger share of the market.
The group – which also takes in Goldsmiths and Mappin and Webb – said it was upgrading its forecast having been helped by strong demand and a cheaper pound increasing the value of its US sales.
The Leicestershire-based business said that in the six months since May it had achieved global sales of £765 million, around a third up on a year before.
