Design
- Case and Dial
- The watch is housed in a 39.5 mm case manufactured from 18-karat white gold. The design is intended to balance classical aesthetics with engineering utility. The argenté solid silver dial features Arabic numerals and a railroad track minutes scale. A pulsometer scale is printed on the outer circumference, a feature identified as referencing early medical chronographs and historical pocket watch designs. The sub-dials are placed slightly below the center line of the dial, which is noted as a signature element for the manufacture.
