Altitude Chronograph Pulsograph Valjoux 23

At its core is a meticulously restored ‘new old stock’ Valjoux 23 – a hand-wound column wheel chronograph calibre originally produced from 1916 and celebrated for its refined architecture and reliability. Each movement has been carefully refurbished and hand-finished in collaboration with Chronode, delivering a contemporary interpretation of traditional haute horlogerie.

The 42mm Trip-Tick case is crafted from lightweight, high-strength titanium, offering durability while maintaining a slim 12.52mm profile for everyday wear. A sapphire exhibition case back reveals the distinctive Y-shaped bridge and intricate finishing of the movement.

The dial draws on classic chronograph design, featuring a warm salmon-pink galvanic finish with a mix of brushed and grained textures. Applied black gold numerals and indexes are filled with white Super-LumiNova® for clarity, while silver sub-dials at 3 and 9 o’clock introduce a subtle two-tone contrast. A pulsometer scale on the dial ring references traditional medical chronographs.

Fitted with a quick-release brown nubuck leather strap with ecru stitching, the Altitude Chronograph Pulsograph balances vintage inspiration with contemporary execution.
