The first watches, often considered "clock-watches," emerged around 1500 in Germany, particularly in Nuremberg, with Peter Henlein (1485-1542) often credited as a key figure in their development. These early timepieces were portable, spring-driven clocks, worn as pendants or on chains, and were more ornamental than accurate. 

Here's a more detailed look at the invention of the watch:

Early Timekeeping:

Before the advent of watches, people relied on sundials, water clocks, and church bells to tell time. 

The Rise of Portable Clocks:

The 15th century saw the development of portable, spring-driven clocks, which were the precursors to watches. 

Peter Henlein and Nuremberg:

Peter Henlein, a German clockmaker and locksmith, is often credited with creating some of the earliest "clock-watches" in his workshop in Nuremberg. 

"Clock-Watches":

These early timepieces were not like modern watches. They were heavy, drum-shaped brass boxes, often decorated and worn on chains around the neck or fastened to clothing. 

Focus on Ornamentation:

These early timepieces were more about fashion and status than accurate timekeeping, with many lacking minute hands. 

Evolution of the Watch:

Over time, watchmaking technology advanced, leading to more accurate and smaller timepieces, eventually resulting in the pocket watch and later the wristwatch. 

The Wristwatch:

The first wristwatch was designed for Queen Caroline Murat of Naples in 1810 by Abraham-Louis Breguet. 

Patek Philippe's Contribution:

Patek Philippe designed a bracelet watch for the Countess Koscowicz of Hungary in 1868. 

Puritan Watches:

In the 17th century, plain, almost egg-shaped watches, known as "puritan watches," emerged in England and the Dutch cities of Haarlem and The Hague. 

Balance Spring:

In 1657, the invention of the balance spring significantly improved the accuracy of watches by turning the balance wheel into a harmonic oscillator, reducing errors from several hours per day to less than 10 minutes. 

The Rise of Pocket Watches:

Pocket watches became popular in the 18th and 19th centuries, with advancements in watchmaking technology leading to improvements in accuracy and durability. 

The Modern Wristwatch:

The wristwatch as we know it today became popular in the early 20th century, with women's fashion playing a role in its popularity.
