Tinted SEM of movement of Timex watch
False colour scanning electron micrograph (SEM) of the movement of an inexpensive watch (made by Timex) showing a close-up of the minute wheel & pinion (bottom) meshing with the hour wheel (top). These comprise part of the motion work of the watch, the train of reduction gears that display the time. A central wheel, connected to the teeth of the barrel (which houses the mainspring) turns once per hour. The no. of leaves & teeth in the minute/hour wheel reduction gives a ratio of 12:1, ie 12 revolutions of the centre wheel will display 12 hours. Magnification: x 8 at 35mm size.

EDITORS COMMENTS
This print showcases the intricate inner workings of a Timex watch in stunning detail. Through the use of false color scanning electron microscopy (SEM), we are granted an up-close view of the mesmerizing movement mechanism. The focus lies on the minute wheel and pinion, located at the bottom, seamlessly interlocking with the hour wheel positioned above it. These essential components form part of the motion work within this affordable timepiece, constituting a train of reduction gears responsible for accurately displaying time. At its core, a central wheel is connected to the teeth of the barrel housing the mainspring, completing one revolution per hour. The minute/hour wheel reduction ratio is ingeniously designed at 12:1, meaning that twelve rotations of this central wheel will precisely indicate twelve hours on our beloved wristwatch. This clever engineering ensures accurate timekeeping while maintaining simplicity and reliability. Magnified eight times at a 35mm size, this image allows us to appreciate every tiny cog and gear that contributes to our daily lives. It serves as a reminder that even familiar objects like watches possess hidden marvels waiting to be discovered under closer scrutiny. This black-and-white print from Science Photo Library offers an artistic perspective on technology's intersection with everyday items without any commercial connotations or reference to Timex as a company.
