From the Original Wheel
to High-End Gear Trains
SECONDS WHEELS
I am the one that carries the second hand.
I am the most precise one — the pinnacle of hand-setting.
Crafting these key components for hand-setting mechanisms is Joray-Wyss speciality .
CENTER WHEEL
A wheel, born from the union of the pinion and the gear. Without the gear train, there would be no division of time.
Through its teeth and its profile, it delivers the exact time.
YELLOW GOLD–PLATED HOUR WHEEL
Here is the wheel that marks the passing of the hours. Sometimes it is dressed in yellow gold, sometimes in rose gold.
Often, its maker does not dress it at all, leaving it exposed to corrosion and staining.
I wouldn’t bet much on its long-term accuracy.
ROSE GOLD–PLATED HOUR WHEEL
Here I am, coated in rose gold! My dimensions are 0.16 mm thick and 8 mm in diameter.
It goes without saying that my makers take great care to achieve such a result.
POLISHED PART
Without the polishing operation, we would be ugly, scratched, and full of burrs.
We would never be able to play our role in a well-oiled movement.
PINION BEFORE ASSEMBLY
I am what they call a “sub-assembly,” just like in the automotive industry.
Once assembled with my wheel, I become part of the famous gear train of time, transmitting energy to my immediate successor, the third wheel.
The hole in the part measures half a millimeter in diameter—machined in steel and over 4 millimeters long—so you can imagine the effort required to produce me!
MOULDED SPOKED WHEEL
This is the very best!
I am cut, rimmed, bevelled, gilded, and my spokes are hand-finished to delight lovers of fine watchmaking.
TURNED AND MOULDED WHEEL
Some of my clients want more for their watch.
My maker carved a moulded recess into my surface to give the movement extra reflections.
Only true connoisseurs will examine me with a specialist’s eye. No matter — even discreet as I am, I contribute to the overall beauty of the piece.
SCREW WITH CONICAL HEAD AND ANGLED SLOT
Back in the 1970s, the quartz crisis had people thinking strangely.
“What? They polish screw heads! But it’s useless!”
Today, not a single high-end watch would do without polished screw heads—the kind that turn heads themselves… Go figure.
