What is a Watchcock?

This page includes large graphics, please be patient.

In the 17th and 18th century Baroque art period, time was less insisting, and artisans of the old world devoted countless hours fashioning intricate covers to protect the delicate balance wheels of fine watches. These covers, or watchcocks were placed on the movement and inside the watch cases, thereafter seen only on infrequent occasions when the cases were opened.

All illustrations are approximately three times actual size.

Each watchcock usually began as a thin piece of brass. Once cut to shape, the round plate was pierced, filed painstakingly and hand engraved with intricate designs, and finally firegilded. The composition of the design was usually very elaborate and based on a star, wheel, rosette, architectural form, or even the artisan's name or initials.

Three Watchcocks

In the design of each watchcock, one may find birds, dragons, dolphins, lions, snakes, cherubs, heraldic and Masonic symbols, bizarre and grotesque faces, mythological animals, baskets of flowers, urns, or even human heads in full face or profile. The most wondrous fact of all is that each watchcock is truly unique.  No two exactly alike have ever been discovered.

So what happened to the watches?

The short answer - they were scrapped for the gold and silver cases.

Long answer -

These watchcocks were used on watches that utilized the verge escapement for timekeeping. The verge escapement required a constant source of power which necessitated the fusee. The fusee in turn made the watch quite thick and bulky.





The verge escapement had been in use since the 1300's. During the 18th century a number of new escapements emerged. The cylinder, the duplex, and most significantly - the lever. All of these escapements were better timekeepers than the verge and none required the fusee so the watches could be thinner.

Almost overnight the verge watch became obsolete and old-fashioned. Everyone who could afford a watch wanted the new thin stylish watches that kept time.

The watchmakers took in the obsolete verge watches and melted down the precious metal cases for scrap. They threw the movements away. But... some of them took the time to loosen one screw and remove and keep the balance cock. These are the watchcocks you see on these pages. The thousands of beautiful watches they graced are gone for good.
