The New Zenith Chronomaster Original Triple Calendar Lapis Lazuli

Zenith‘s Triple Calendar model is based on the compact 38mm case of the Chronomaster Original, itself modelled after the 1969 El Primero reference A386. This reference provides a balanced and wearable foundation for a relatively complex movement. Initially launched in stainless steel (2024) and subsequently in rose gold (2025), Zenith has decided that it was time to embrace the current trend for stone dials, and brings one to reflect the theme of the brand’s 160th anniversary celebrations: Blue. Here’s the Lapis Lazuli edition of the Chronomaster Original Triple Calendar. 

The new Chronomaster Original Triple Calendar with lapis lazuli dial sits at the upper end of Zenith’s regular production lineup, justified by its material complexity, integrated mechanical functionality, and the use of a case architecture faithful to one of the brand’s most historically important designs. The execution remains consistent with Zenith’s emphasis on high-precision chronometry as the watch continues the brand’s ongoing exploration of traditional complications paired with its high-frequency chronograph platform, and the use of blue.

The latest edition retains the stainless steel construction used in the classic releases, with dimensions of 38mm in diameter, 14mm in thickness, and 46mm lug-to-lug. The finish alternates between polished and brushed surfaces, and water resistance is rated at 50 meters, adequate for daily wear, though clearly not designed for aquatic adventures.

The lapis lazuli dial introduces a decorative element without compromising technical integrity. Using natural stone poses manufacturing challenges due to its brittleness and requires precise machining and structural reinforcement to ensure durability. In this configuration, the lapis base harmonises with silver-toned subdials and rhodium-plated, faceted markers and hands coated with SuperLuminova SLN C1 to preserve low-light legibility. The dial follows the tri-compax layout typical of the El Primero, with subdials at 3, 6, and 9 o’clock. At 3 o’clock is the chronograph seconds counter, while the 6 o’clock register combines a 60-minute chronograph totaliser with a moon-phase aperture. Running seconds are located at 9 o’clock, and the central chronograph hand makes one rotation every 10 seconds, enabling 1/10th-of-a-second resolution.

The complete calendar is neatly integrated, with the day displayed at 10 o’clock, the month at 2 o’clock, and the date window between 4 and 5. Despite the information density, the dial remains legible and well-proportioned, with clear typography and precisely executed cutouts that preserve visual symmetry.

Inside is the El Primero 3610, an automatic column-wheel chronograph movement with a lateral clutch. It operates at 36,000 vibrations per hour (5 Hz), enabling high-frequency timing and the signature 1/10th-second chronograph functionality. It features a stop-seconds mechanism for precise time-setting and offers a 60-hour power reserve via a single barrel. Visible through the sapphire caseback, the movement includes Zenith’s star-shaped oscillating weight with a satin finish, though the overall decoration is restrained in keeping with the watch’s technical orientation.

The Chronomaster Original Triple Calendar Lapis Lazuli is worn on a blue calfskin leather strap with a folding clasp, or a stainless steel bracelet with a folding clasp, enhancing versatility – both are included. Prices are CHF 21,900 or EUR 23,700. For more details, please visit www.zenith-watches.com.
