Both ‘Le Régulateur’ and ‘La Semaine’ share the same 40mm titanium watch cases. The case architecture consists of a frame with vertical sidebars known as “brancards,” flanked by a conical crown. Visual balance and intrigue are achieved through contrasting shapes, materials, and finishes, starting with micro blasted and polished grade 2 and grade 5 titanium.

Each model is water-resistant to 100 meters, and each comes equipped with an easy-wearing, quick-fit double-layer nylon strap.

All watches also feature a Stephen Silver logo engraved on the sapphire crystal case back, which reveal a glimpse of the watches’ automatic movements. The Louis Erard x Alain Silberstein for Stephen Silver La Semaine watches also offer 38 hours of power reserve.

These limited-edition watches feature the emblematic Alain Silberstein design elements, with his signature use of elementary forms and primary colors. Jared Silver also worked with Louis Erard to develop an iridescent blue sapphire inspired minute track exclusively for this limited edition, inspired by the many exceptional sapphire gemstones in the Stephen Silver Fine Jewelry collection.

Le Régulateur presents a large white arrow hand for the minutes, a red triangle for the hours, and a small yellow serpentine hand for the seconds, and La Semaine, with its three hands, date, and day displays, offers Silberstein’s special take on the weekly planner.

Rather than traditional dates, the window presents playful smileys from grey Monday to radiant Sunday. The smiley mood on display can be tailored to the wearer’s schedule.
