Founded in 1929, Louis Erard is a watchmaker that is filled with heritage and history. Acquired in the 1990s before it was relaunched during the independent watchmaking boom of the early 2000s, in 2003, the brand has established a strong design language that doesn't break the bank. Since then, Louis Erard has built a passionate customer base that continues to grow thanks to the popularity and success of their collaborative projects and impressive individual exploits. One of their most successful collaborations is with famed French designer and watchmaking industry veteran Alain Silberstein. Released in 2022 as Louis Erard's third collaboration with Alain Silberstein, the Le Triptyque Louis Erard x Alain Silberstein was a collection of three different timepieces that each featured a unique set of functions and layout while also being limited to just 178 pieces each. Offered here, we have the Day-Date variant, or the La Semaine Blanche as it is known, that follows on from the pair's original 2019 collaboration. Featuring a 40mm case, the La Semaine Blanche is an exceedingly unique timepiece with vertical sidebars or 'brancards' that are not a common sight in watchmaking. Made from micro-blasted grade 2 titanium, its lugs, case, and bezel all sport a matte finish, while its grade 5 titanium vertical sidebars feature a polished finish. Sporting an incredibly unique dial, the La Semaine Blanche’s opaline silver dial features Alain's visual style in abundance. With multi-colored whimsical-shaped hands made from various shapes, the La Semaine Blanche blends yellow with red and blue to create a visual delight and allow each constituent of its display to remain clear, and legible. Building on this whimsical take on timekeeping, the La Semaine Blanche also features a Day and Date display. While its date display is a rather classical numerical representation of the date in an aperture at 6 o’clock, the day display is rather Silberstein-esque. Instead of merely stating the day, the La Semaine Blanche features seven different colored faces that feature various emotions as the days progress and the weekend beckons closer.

Unmistakably Silberstein-esque, the La Semaine Blanche's colorful dial furniture and unique day display mean there is certainly no doubt about who designed this terrific timepiece.


A tonneau-shaped construction of sorts, the La Semaine Blanche's brancards accentuate its polished circular case, thus allowing it to take center-stage alongside its colorful dial. Furthermore, its rotatable strap attachment allows it to wear snug as its strap drapes down across the wearer's wrist.

Our Perspective

A fantastically unique timepiece, as we would expect from Alain Silberstein, the La Semaine Blanche marries Louis Erard's eye for detail and rich heritage with Alain's aesthetic and whacky take on horological design in a manner that is abundantly appealing.
