On the Smile-Day Blue, designed with Alain Silberstein, a smiley at 6 o’clock shows the mood of the day: black on weekdays, red at the weekend.
Louis Erard today introduces the Louis Erard x Alain Silberstein Smile-Day Blue. With a Tourbillon Régulateur Blue, it opens the Hall of Fame, a new permanent collection produced in limited annual quantities.

Silberstein’s signature hands stand out on the blue sunray dial: a red triangular hour hand, a white arrow-shaped minute hand and a yellow serpentine seconds hand.
The 40mm case is microblasted and polished titanium, on a heathered blue nylon strap that closes with Velcro directly on the nylon. Inside is the automatic Sellita SW220-1, with approximately 38 hours of power reserve.
“Our collaborations with Alain Silberstein are never ordinary. They are stories to be worn on the wrist, where every detail matters,” says Manuel Emch, who leads Louis Erard.
It is the first watch in a collection Louis Erard means to keep making, a small number of pieces at a time, every year.
