A Named Commercial Line
The Wiener Schach-Zeitung equipment catalog of 1932 offered two clocks under the names Wienerin and Wienerin-Lux. The catalog identifies features, prices, and ordering terms, but not the manufacturer.
The Standard Wienerin
The standard clock was described as having a precise movement, pearwood case, side-mounted controls, decorative enameled and gilded pushers, and flag-fall indicators. It was clearly built for regulated competitive play.
The Lux Version
The Wienerin-Lux retained the same basic timing function while upgrading the case to mahogany and adding more ornamentation. Its price rose from 15 to 20 Reichsmarks.
Product Differentiation
The additional cost did not buy a new time-control system; it bought materials, finish, and status. Chess timing had matured enough that sellers could differentiate products aesthetically while leaving the mechanics fundamentally unchanged.
International Sales
Ordering instructions extended beyond Austria into Czechoslovakia, Poland, Yugoslavia, and other markets, showing that the line was conceived for a broader Central European chess audience.
Historical Significance
The Wienerin demonstrates that a chess clock could simultaneously be a precision instrument, a branded product, and a luxury object. The safest attribution remains a line marketed by the Wiener Schach-Zeitung rather than a proven in-house manufacture.
