PRODUITS

SECOND WHEEL SETS

 

The second wheel set carries the second hand. It is the most accurate of all the watch hands. At Joray-Wyss, we specialise in producing hand-fitting cogs.

CENTRE WHEEL SETS

 

A wheel set is the union of pinion and wheel. Without cogs, there would be no division of time. Its teeth and profile give us the exact time.

 

YELLOW GOLD-COATED HOUR WHEEL SETS

 

This is the wheel set that counts down the hours. Sometimes, it is coated with yellow gold, sometimes with pink gold. Often, the watchmaker decides not to gild them at all, and they become rusty and stained. In this case, they are unlikely to guarantee precision in the long term.

 

PINK GOLD-COATED HOUR WHEEL SETS

 

Here is a pink gold-coated hour wheel. It is 0.16 mm thick and measures 8 mm in diameter. Naturally, the master watchmakers take the utmost care over these components to achieve this exceptional result.

 

POLISHED PARTS

 

The polishing process turns plain, scratched and rough parts into smooth, bright parts which play their part perfectly in a well lubricated movement.

 

PINIONS PRE-ASSEMBLY

 

These pinions are “sub-assemblies” as they are known in the automotive industry. Once the pinion is assembled onto the wheel, together they form the familiar watch cog; this transmits energy to the next wheel, called the third wheel. The hole in this steel part measures half a millimetre in diameter, and is 4 millimetres long – a real feat of engineering!

 

WHEELS WITH CHAMFERED ARMS

 

For customers who have a real eye for fine watchmaking, the process of creating these parts involves cutting, circular-graining, chamfering and gilding, plus bevelling on the arms ‘a true chef-d’oeuvre!

 

MACHINE-CHAMFERED WHEELS

 

Some of our watch customers want to go above and beyond. Our master watchmakers can machine a chamfer into the surface of the wheel to create a play of light in the movement. Only true connoisseurs will appreciate this expert touch. But however subtle this detail, it adds to the overall beauty of the piece.

 

COUNTERSUNK SCREWS AND SCREWS WITH CHAMFERED SLOTS

 

In the 1970s, the watchmaking industry noticed an alarming development: screw heads began to be polished. Some argued that this was pointless. Nowadays, however, most high-end watches feature polished screws and it is seen as an attractive design element… how times have changed!
