What would the railroad chronometer have become if its development had never stopped?
The 950C is built on the same architecture as the finest American railroad pocket watch ever made. Same 16-size format. Same lever-set operation. Same six-position adjustment discipline. Same proportions. Every component interchangeable with a vintage original in both directions.
The only changes are the materials — substituted where modern alloys offer a measurable performance benefit with no change to operation. And one deliberate enhancement: a micrometric regulator on the balance cock, making precise rate adjustment accessible to any skilled enthusiast without specialist tools.
The 950C is what the original would have become if its development had never been interrupted. Build it right. Keep it alive.
Center, third, fourth, and escape wheels precision-machined in titanium. Reduced rotational inertia across the full power path. A material improvement any railroad watchmaker would have made immediately if it had existed.
Direct replacement in the stock single barrel. Superior elasticity, no magnetic susceptibility, will not set over time. Power reserve is measured from a running movement — not engineered to a number.
Contemporary alloy improves temperature stability and magnetic resistance. Architectural drop-in — no geometry change, no change to the balance assembly.
Same geometry as the original. Silicon eliminates lubrication requirements at the escapement, improving long-term rate stability without any change to how the movement is serviced.
Substituted on the balance cock only. A screw to turn rather than a lever to slide. Precise, repeatable, accessible to a careful enthusiast. Everything else on the balance cock is standard original geometry.
White zirconia base, fired enamel finish, underglaze printing. Impervious to UV, moisture, and age. The numerals are in the material, not on it. The modern continuation of the same logic that produced enamel dials in the first place.
The deadman dial. Bold Arabic numerals large enough to read in a moving locomotive cab. Double-sunk construction — recessed center platform, further-recessed sub-seconds register at 6 o'clock. Full 60-second minute track at the outer edge.
Lume on hands only. High contrast. No decoration that does not serve legibility. The dial will outlast the movement.
Lever clearance maintained throughout — the dial accepts a vintage original movement or a 950C movement without modification.
A 950C movement installs in a vintage case. A vintage movement installs in a 950C case. Dials interchange in both directions. The setting lever clearance is maintained. The stem geometry is identical.
This is the primary constraint of the project — not an afterthought, not a marketing angle. It means the 950C can donate parts to keep a vintage original running, and a well-preserved vintage movement can live in a new case. Both are kept alive.
