A Unitas 6498 movement, hand-skeletonized and finished by Jochen Benzinger on rose engines in Pforzheim. The base plate is electroplated in ruthenium — a dark, mirror-like finish often called “black gold” — and engraved with the TWC signature at four o’clock, set into the openwork itself. 42 mm polished steel case, sapphire front and back; assembled in Maryland in editions of roughly 25 per year.

Black Gold & Guilloché
The HALF-SKELLY’s base plate is electroplated in ruthenium—creating a dark, mirror-like finish that deepens the guilloché. Each cut from Benzinger’s rose engine catches light beneath the blackened surface, revealing craft through contrast.
Ruthenium is a rare, platinum-group metal used in high-end watchmaking and jewelry, especially for electroplating. When applied to gold via electroplating, it creates a dark, metallic finish—what’s often called black gold. This finish isn’t painted or oxidized; it’s a bonded surface layer achieved by submerging the gold part in a ruthenium solution and running an electric current through it.

In 2014, while restoring Abraham Lincoln’s gold pocket watch at the Smithsonian, Towson co-founder George Thomas found an inscription etched inside the case-back by watchmaker Jonathan Dillon in 1861 — a secret message that had been hidden for over 150 years.
The HALF-SKELLY carries its own intentional mark in the same spirit. At four o’clock, the TWC initials are cut into the skeletonized base plate behind the 6498 movement, visible through the openwork.
