Bremont continues the expansion of its modern aviation-focused Altitude collection with the introduction of the Altitude Chronograph Pulsograph Valjoux 23, a limited-edition chronograph built around one of watchmaking’s most respected historic calibres.
Limited to just 40 pieces worldwide, the release combines a restored new old stock Valjoux 23 movement with Bremont’s contemporary titanium Trip-Tick case architecture, creating a watch that deliberately balances vintage chronograph character with modern construction standards. Positioned as one of the most horologically ambitious additions to the Altitude family to date, the watch draws heavily from mid-century sporting chronographs while avoiding direct historical recreation.

A New Chapter Within The Altitude Collection

Introduced in 2025 as the evolution of Bremont’s MB aviation series, the Altitude collection expanded the brand’s signature engineering language into a broader family of contemporary tool watches inspired by flight and adventure. The Altitude Chronograph Pulsograph follows earlier releases such as the Altitude Perpetual Calendar in exploring more traditional haute horlogerie territory through the lens of Bremont’s modern technical identity. Here, the focus shifts toward classical chronograph watchmaking, particularly the visual and mechanical language associated with some of the most admired chronographs of the 1930s and 1940s.

The Return Of The Valjoux 23

At the centre of the watch is the legendary Valjoux 23 movement. Originally introduced in 1916, the hand-wound calibre became one of the defining chronograph movements of the twentieth century, used historically by some of Swiss watchmaking’s most important maisons, including Patek Philippe, Rolex, Audemars Piguet and Vacheron Constantin. For this release, Bremont collaborated with Chronode, the atelier founded by Jean-François Mojon, to source and restore 40 new old stock Valjoux 23 ébauches. Each movement has been meticulously refurbished, assembled, regulated and hand-finished specifically for the project.
Rather than applying strictly traditional decorative techniques, Bremont opted for a more contemporary finishing approach combining fine-grained surfaces with polished bevels and mirror-polished details that visually connect with the textures found across the dial.

A Dial Inspired By Vintage Medical Chronographs

The strongest vintage influence appears on the dial. Rendered in a warm salmon tone, the display references the aesthetic language of mid-century chronographs while incorporating modern detailing and finishing complexity.
A vertically brushed central section contrasts against a grained outer area, while polished black gold stencil-style numerals filled with Super-LumiNova add further dimensionality.
Two silver-toned subdials create a restrained panda-style layout, including a running seconds display featuring Bremont’s signature three-pronged propeller motif. Surrounding the dial is a pulsometer scale, a direct nod to historic doctors’ chronographs traditionally used to measure heartbeats. Many of those original pulsographs were themselves powered by the Valjoux 23, creating a historically coherent connection between movement and display.

Titanium Trip-Tick Construction

The watch is housed within Bremont’s signature Trip-Tick case architecture, here executed in lightweight titanium. Measuring 42mm in diameter with a relatively restrained thickness of 12.52mm, the case benefits directly from the slim proportions of the Valjoux 23 movement.
The titanium construction helps reduce overall wrist weight while preserving the structural presence associated with the Altitude collection. Despite its vintage inspirations, the watch remains firmly contemporary in execution, combining modern materials, manufacturing precision and Bremont’s rugged engineering philosophy.

A Contemporary Interpretation Of Heritage Chronograph Design

Rather than attempting a direct recreation of a vintage reference, the Altitude Chronograph Pulsograph instead explores the hybridisation of historical design codes and modern watchmaking. That tension between old and new defines much of the watch’s appeal. The salmon dial, pulsometer scale and hand-wound chronograph movement reference classical chronograph collecting culture, while the titanium case construction, contemporary finishing and Altitude architecture anchor the watch within Bremont’s modern identity. The result is a chronograph that feels intentionally transitional, equally connected to twentieth-century chronograph history and contemporary tool-watch design.
