Jean Arnault, director of Louis Vuitton’s watch division, has to contend with a tough luxury market and stubborn young consumers.

LVMH, which is controlled by the family of multibillionaire Bernard Arnault, was a major sponsor of the Summer Games in Paris.

While millions know at this point that Melania Trump adores Dior, it seems that Ivanka has a soft spot for the European house, too. The former West Wing adviser wore a Dior dark forest green skirt suit with a thin black belt and a coordinating beret-style hat to the Inauguration ceremony at the U.

The medals were designed by a jewelry maker owned by the French luxury conglomerate, which has declined to comment on their deterioration.

Novo Nordisk has faced a massive selloff in recent months amid disappointing drug trials and U.S. pressure to cut its prices.

At LVMH Watch Week, Daniel Roth debuted its latest timepiece, the Extra Plat Souscription. Inspired by its Tourbillon Souscription watch, Daniel Roth has reinterpreted the design in a new laidback way – but as a limited edition novelty, you might not be able to get one.

LVMH said on Tuesday it was "impossible" to control the final destination of products sold by third-party distributors after a report said the French luxury group's champagne reached Russia even after it halted business there.

The rest of the top ten largest companies in Europe by market cap include ASML ( ASML ), SAP SE ( SAP ), Hermès International ( OTCPK:HESAY ), Roche Holding AG ( OTCQX:RHHBY ), Accenture plc ( ACN ), Nestlé S.A ( OTCPK:NSRGY ), AstraZeneca PLC ( AZN ), and Novartis AG ( NVS ).

The U.S. market’s importance was underscored by striking models pushing watchmaking boundaries in design and technical prowess.

The 44mm brushed steel case is classically Panerai with its squircle design and oversized crown guard. The dial is also brushed and blue in colour, with accents in yellow to contrast nicely. That's surrounded by a blue ceramic bezel, and matches nicely with a rubberised crown and rubber strap, too.

The Olympic medals, which were designed by Chaumet, a luxury jewellery and watch maker and part of the LVMH group, are tarnishing – and the luxury giant has fallen silent.
