完整圖錄內容
BALTIC Experiments is Baltic’s platform for exploring new materials, technical solutions and more unconventional expressions of watchmaking. It is offered here as a first-time production prototype of an as-yet unreleased watch.
Developed in 2026, the Stepgraph takes its name from the distinctive architecture of its case. Measuring 37 mm in diameter, the design combines softly rounded and curved case flanks with a stepped bezel and caseback, creating a profile that shifts between fluid surfaces and sharply defined levels.
The present prototype also marks BALTIC's first exploration of tantalum as a case material. Dense, rare and particularly demanding to machine, tantalum possesses a distinctive deep grey tone with subtle blue reflections, giving the watch an appearance quite unlike that of conventional material.
Tantalum is paired here with a blue mother-of-pearl dial with grown lab diamond indexes, whose changing reflections echo the cool tones of the case. The result is a watch whose character is defined as much by its materials as by its form.
The Stepgraph “Nacre Nocturne” represents an exploration of materials drawn from the earth: the mineral depth of tantalum meeting the organic iridescence of this dark blue mother-of-pearl.
As a unique prototype of an unreleased model, the present example occupies a singular place in the development of BALTIC Experiments and in the history of the brand.
