International Time Recording Clock Value Guide

This International Time Recording clock is a significant piece of industrial history, representing the early evolution of the company that would eventually become IBM. As a 'slave clock,' it served as a vital component in synchronized timekeeping systems used to maintain strict punctuality across 20th-century factories and schools.

What affects the value of International Time Recording Clock?

• Condition of the original paper dial, as yellowing, tearing, or water damage significantly impacts the $180-$220 valuation.
• Integrity of the glass cover and the preservation of the dark brown factory finish on the metal housing.
• Presence of original internal wiring and mechanical components, even if the clock requires a master pulse to operate.
• Historical provenance or markings indicating the specific industrial or commercial facility where the clock was originally installed.

How to Identify International Time Recording Clock?

• Look for the 'International Time Recording Co.' or early 'IBM' branding on the paper dial face.
• Verify the dark brown metal casing which is characteristic of industrial Art Deco office equipment from the 1920-1940 era.
• Check for the absence of a standalone winding mechanism, as these units were designed to be wired to a central master clock system.
• Confirm the 'Made in U.S.A.' stamping typically found at the bottom of the dial or on the internal movement.

History of International Time Recording Clock

International Time Recording Company, founded in 1901, quickly became a leader in timekeeping devices. In 1911, ITR merged with Computing Scale Company and Tabulating Machine Company to form Computing-Tabulating-Recording Company (CTR), which later became International Business Machines (IBM) in 1924. This clock, often referred to as a "slave clock," would have been part of a synchronized system in large commercial or industrial settings, ensuring all clocks displayed the exact same time, controlled by a master clock. These systems were crucial for maintaining punctuality and efficiency in factories, offices, and schools during the early 20th century.
