Pocket Sundial

We are using wristwatch now a day to keep a look at time in every day life. But, the history of  innovation of this miniature clock was not so smooth. During the time of it`s first development, wristwatch was facing lots of difficulty in accuracy for mechanical backlogging. It takes time to make a wristwatch with supreme perfection and became what it is now today.

The development of mechanical wristwatch began at Renaissance periods while Europe became increasingly trade oriented and business booms demands a accurate time time keeping device. Businessman and and traders movement becomes intense and they require a potable watch; but the armature mechanical watch cant satisfy their need. This continual pressure pressed the watchmaker to think of a different technology rather than blindly rely upon mechanincal technology to invent a potable clock.

What they came with is a millennium old technology of time-keeping: sundial and they perfected it to a pocket sundial. Since, the innovation,  pocket sundial become a very popular instrument collected by trader, craftsman and elites of European society. During earlier stage, those pocket sundials could be used only during day because sundial depends upon sunlight to measure time from shadow casted by it`s gnomon.

The Swiss watchmakers later perfected this pocket sundial usable during night as well in streetlights, gas lamp and even with a cigarette lighter. As it become more and more popular in Renaissance Europe, Pocket sundial become available for ladies and it became more as jewellery item than timepieces.The mechanical wristwatch also perfected after few decades and market domination of pocket sundial got gloomy.

Now a day, people uses pocket sundial as a instrument of antique and curiosity. These sundials are generally made of copper and brass and come up with built-in magnetic compass to be oriented north. The gnomon of this dial cast a shadow in sunlight and marks the local time by in the dial marked with 1 to 12 hrs. Some are ornamented with different designs and very handy with average weigh of 85 grams.
