Cameel Halim is a respected presence in the Chicago real estate sphere who has overseen numerous development projects that achieved urban restoration goals. Cameel Halim is currently in the process of launching the Halim Time & Glass Museum. The museum features glass pieces by noted manufacturers such as Thomas Webb & Son, as well as antique timepieces.

The pocket watch has its origins in the early 15th century, when a coiled spring was invented in Germany as a way of increasing functionality in locks. The spring quickly crossed over to the clockmaking sphere, as it allowed a device to be wound in ways that stored energy for release over an extended period.

While the main spring enabled the creation of clocks small enough to fit in the hand, it did not solve the issue of a movement that ran at a constant rate as the spring wound down. With the “Nuremberg Egg,” an egg-sized timepiece introduced around 1530, for decades time deviations each day were measured in the hours, rather than in minutes.

This all changed in 1675 with Christiaan Huygens’ invention of the “hair spring” or “balance wheel” mechanism, which absorbed energy output from the main-spring and released it at a constant rate that ultimately allowed the creation of minute hands.
