A Celestial Companion: Montblanc’s Bohème Perpetual Calendar

Montblanc’s Bohème collection has always captured the refined spirit of the free-spirited woman, and with the new Bohème Perpetual Calendar, the Maison translates one of watchmaking’s most revered complications into a feminine masterpiece.

At 36mm, the case, crafted either in solid 18K rose gold or in a bi-metal combination of stainless steel and rose gold, frames a dial that is as poetic as it is technical. Four subdials—arranged with a deliberate elegance that softens the traditionally rigorous architecture of the perpetual calendar—track the day, date, month, leap year cycle, and moon phase. Each indication rests on a mesmerizing field of micro-diamonds, their uniform surface coated with a metallic PVD treatment that shimmers like a starlit sky.

Encircling this celestial stage is Montblanc’s “filé d’étoiles” pattern—a trail of stars echoing the Earth’s cosmic dance, inspired by long-exposure astrophotography. A watercolor-style moon disc at six o’clock adds a painterly touch, reminding the wearer of time’s quiet poetry. Rose gold-coated leaf hands and floral Arabic numerals ensure the dial remains both legible and elegant.

Technical mastery underpins the artistry: Montblanc’s calibre MB 29.15 powers the watch, offering hours, minutes, full perpetual calendar functionality, and a 42-hour power reserve—requiring no correction until 2100. The bezel is adorned with 60 brilliant-cut diamonds, each serving as both adornment and precise minute markers.

Delivered with three interchangeable calfskin straps—beige, black, and burgundy—the Bohème Perpetual Calendar adapts with ease to every mood. More than a watch, it is an heirloom of artistry and accuracy that marries Montblanc’s fine watchmaking with its heritage of inspiring timeless elegance.
