Louis Erard and Alain Silberstein Join Forces to Present a Special Khaki Trio

Following their successful collaborations in 2021 and 2022, Swiss watchmaker Louis Erard and French designer Alain Silberstein have come together, once again, to create a new set of three watches, including a tourbillon. Not just an ordinary tourbillon, but one coupled with a regulator display. The trio — that all sport charming khaki dials with bright spots of colour — include La Semaine Louis Erard x Alain Silberstein Khaki (Ref. 75357TT06.BTT89), Le Régulateur Louis Erard x Alain Silberstein Khaki (Ref. 85358TT06.BTT89), and Le Régulateur Tourbillon Louis Erard x Alain Silberstein Khaki (Ref. 89356TT06.BTT89).

The first two models are available for purchase individually, in limited editions of 178 pieces, while the tourbillon is only available as part of a triptych box, limited to 78 pieces. The khaki colour on the three novelties instantly stands out; both on the dial and on the strap. All three novelties are housed in 40 mm cases crafted from microblasted grade 2 titanium and polished grade 5 titanium. The timepieces’ conical crowns at 3 o’clock bear the Louis Erard symbol.

The first model in this collection features Smiley's weekly calendar, Alain Silberstein's emblematic calendar where every day has its own face. In fact, the days do not have names; they have playful smileys instead: small, stylised faces symbolising different moods (a particular expression for each day of the week).

La Semaine is powered by a customised automatic Sellita SW220-1 calibre that is visible through the transparent porthole of the caseback. Running at a frequency of 4Hz (28,800 vibrations per hour), it offers a 38-hour power reserve built by the special openworked oscillating weight with a black lacquered Louis Erard symbol.

The second timepiece has a large white arrow hand for the central minutes, a red triangle for the hours at 12 o'clock, and a small yellow serpentine hand for the seconds at 6 o'clock. The self-winding regulator-type Sellita SW266-1 calibre is personalised with an openworked oscillating weight with black lacquered Louis Erard symbol. It operates at a frequency of 4Hz (28,800 vibrations per hour) and has an autonomy of 38 hours.

The final timepiece flaunts a tourbillon, a debut for the timepiece maker. The tourbillon comes coupled with a regulator display. Here, a tourbillon mechanism places the regulating organ (the spring balance) and the escapement inside a carriage that rotates around itself and distributes the oscillations of the balance wheel over 360 degrees.

Showcased through the transparent sapphire crystal caseback, the BCP T02 tourbillon regulator movement is manufactured by the Swiss atelier of Olivier Mory of BCP Tourbillons in La Chaux-de-Fonds. Beating at a frequency of 3 Hz (21,600 vibrations per hour), it offers a remarkable power reserve of approximately 100 hours. All three watches are finished on straps made of special nylon and are equipped with a microblasted grade 2 titanium, and spring bars that allow the strap to be changed quickly.
