Watches of Switzerland taps into lab-grown diamond boom in jewellery push


Luxury retailer Watches of Switzerland has seen annual profits jump 76% and forecast further strong sales over the year ahead as it moves further into jewellery amid the boom in demand for lab-grown diamonds.

The group, which sells high-end Rolex and Omega watches, reported pre-tax profits of ยฃ133 million for the year to May 3, up from ยฃ76 million the previous year.

It said annual sales surged by 13% to ยฃ1.83 billion, with growth of 24% in the US helping offset tougher trading in the UK and Europe, where revenues lifted 5%.

Chief executive Brian Duffy said its UK home market is โ€œshowing encouraging signs of improvementโ€.

Watches of Switzerland (WoS) is expanding into luxury jewellery, with its first jewellery showroom opening recently with the Mappin & Webb boutique in Manchester.

โ€œThis marks an important step in the development of our jewellery strategy and reflects our confidence in the longโ€‘term opportunity in this category,โ€ according to the group.

It has also launched a lab-grown diamond offering in the UK through its Goldsmiths brand to tap into the boom in demand for the gems, which the firm said was โ€œresonating with consumersโ€.

It saw luxury jewellery sales race 17% higher in 2025-26 after notching up growth of 12% in the UK and 26% in the US.

As well as Roberto Coin, the group has house jewellery brands of Goldsmiths, Mappin & Webb, Mayors and Betteridge.

WoS is forecasting further group-wide sales growth over the new financial year, with revenues expected to rise by 5% to 10%.

Trading in the first 10 weeks of the financial year has been โ€œencouragingโ€, it added.

โ€œWhilst we remain mindful of the geopolitical environment, we have carried good US momentum into the new year and see encouraging signs the UK market is improving,โ€ the group said.
