Louis Erard x Alain Silberstein collaborated to create three signature limited edition timepieces — the La Semaine, Le Régulateur II, and Le Chrono Monopoussoir — and well as a Le Triptyque set including all three.

Each of the three references is limited to 178 pieces, 78 of which will be sold in a collector’s box that contains all three watches, as well as digital artwork signed by Alain Silberstein. The collector’s set also includes a non-fungible token (NFT) linked exclusively to each triptych.

The NFT token guarantees and protects the authenticity of the limited edition set, as well as containing all its technical specifications. In addition, collectors will have the opportunity to customize their digital token with a private message.

All three Louis Erard x Alain Silberstein limited edition timepieces feature 40 mm diameter micro-blasted grade 2 titanium & polished grade 5 titanium cases with lengths of 47 mm lug-to-lug and lug width of 22 mm. The La Semaine and Le Régulateur II models have a thickness of 11.6 mm while the more complicated Le Chrono Monopoussoir measures 13.9 mm tall.

The La Semaine is powered by an ETA 2836-2, the Le Régulateur II is powered by a Sellita SW266-1, and the Le Chrono Monopoussoir is powered by a Sellita SW500MPCa movement. All three calibers are automatic and run at 4Hz.

As with the Louis Erard x Alain Silberstein Regulator that debuted as a 175 piece limited edition in 2019, the dial of each of these 2021 editions is matte black and adorned with Silberstein’s signature bright red, yellow, and blue colors — and his unique triangle, circle, and rectangle-shaped hands and indices.

Retail is $3,900 for the La Semaine and Le Régulateur II models, $5,000 for the Le Chrono Monopoussoir, and $12,389 for the set of all three.
