A Little Technical Information
This beautiful porthole clock has a highly accurate quartz movement. I often wondered what that meant. I remember seeing quartz in school and it was a crystal kind of rock! How can that run a clock? Well let's get technical for a moment.
Clocks measure time in units of hours, minutes and seconds. To measure these units, all clocks must have two things: a regular, repetitive resonator, or oscillator, to mark off equal units of time; and a way of displaying those units in an understandable form.
Most time pieces today keep time by applying electric energy to a quartz crystal, a system developed in the 1930s! The energy makes the crystal vibrate or oscillate at a constant frequency and produce regular electric pulses that regulate a motor. The motor advances the watch hands or, in a digital watch, the number display, by one-second increments.
Mechanical watches use a coiled mainspring for power. The mainspring drives gears that cause a hairspring to oscillate, rocking a lever to and fro. The lever drives other gears that move the hands.
OK, that's all fine and dandy. All that technical stuff aside, just admire the beautiful nautical look of this clock and imagine how it would look on your wall, bringing that shipshape feel to your home.
