Time Capsule I weighs about 800 pounds (360 kg), while Time Capsule II weighs about 400 pounds (180 kg). [5] Time Capsule I was made of a non-ferrous alloy called Cupaloy, created especially for this project. [6] Designed to resist corrosion for 5,000 years, the alloy was made of 99.4% copper, 0.5% chromium, and 0.1% silver. [7]
Clockwork damage can be inflicted via over-winding, interaction with contaminants, ill-advised lubrication, and clock movement when a pendulum is not secured prior to the clock being moved. A free swinging pendulum can itself be damaged and can inflict damage onto other interior components during such clock movement.

The following is a list of notable companies that produced, or currently produce clocks. Where known, the location of the company and the dates of clock manufacture follow the name. In some instances the "company" consisted of a single person.
The school opened up a time capsule 942 years before its intended opening date. The capsule was found during construction of a new MIT building. Clearly visible, right there, ...
The most accurate pendulum clocks were controlled electrically. [166] The Shortt–Synchronome clock, an electrical driven pendulum clock designed in 1921, was the first clock to be a more accurate timekeeper than the Earth itself. [167] A succession of innovations and discoveries led to the invention of the modern quartz timer.
