How are hair springs made?
How are hair springs made?
Conventional Hairsprings are made of iron-nickel alloys such as Nivarox, whose elasticity is almost unaffected by temperature. Combining high tech industrial precision and manual work, hairsprings are manufactured through ultra-precise metal lamination techniques to produce a malleable blade.
How are balance springs made?
Modern balance springs are made of special low temperature coefficient alloys like nivarox to reduce the effects of temperature changes on the rate, and carefully shaped to minimize the effect of changes in drive force as the mainspring runs down.
What material is a hairspring made of?
In 1933, Reinhard Straumann invented the Nivarox alloy, a German acronym meaning “not variable, not oxydizable”. With its very complex composition (iron, nickel, cobalt, chromium, titanium, beryllium and so forth), it quickly became the perfect material for hairspring manufacturing….

Who invented the hairspring?
In short, Hooke invented it, Huygens perfected it. After 350 years, the strange case of the hairspring’s invention has finally been settled in favor of the hateful, haughty, thieving Robert Hooke – both the villain and the victim in this ironic twist of horological history.
What are watch springs made of?
Modern mainsprings A modern watch mainspring is a long strip of hardened and blued steel, or specialised steel alloy, 20–30 cm long and 0.05-0.2 mm thick.
How much does a watch spring cost?
A new mainspring costs about $45.00 and up. If needed, cleaning and oiling runs about $160.00 and up. For old pocket watches basic cleaning & oiling costs around $200.00 and up. Due to extreme price increases, most mainsprings for pocket watches now cost $80.00 or more installed.
What is Silicon hairspring?
The most common use of silicon in a watch movement is the balance spring or hairspring. The combination of these two parts together is called the oscillator. The hairspring is one of the smallest components in a watch but also is one of the most critical in keeping the watch precise.
How are clock springs made?
Clock springs, also known as a power springs, are made by winding a pre-stressed flat strip of spring material on an arbor and into a retaining ring to create a compact power source.
Are clock springs expensive?
The average clock spring replacement cost is between $100 and $800, depending on the car model and labor costs. A clock spring costs $50 to $500, and the labor costs $50 to $300. The big difference in the price is because some car models have the clock spring integrated with some control modules for the steering wheel.
How much does a clock spring replacement cost?
Clock Spring Replacement Cost Clock springs are relatively inexpensive, running between $50 and $200 depending on the vehicle. Labor is fairly straightforward and should take 1-2 hours; expect to pay up to $300 in labor.
Are silicon Hairsprings good?
It improves stability, performance, accuracy, and resistance to magnetic interferences and thermal fluctuations. It also can keep its shape forever and never requires any lubrication. The most common use of silicon in a watch movement is the balance spring or hairspring.
Does Rolex use silicon?
The 2014 Rolex Datejust Pearlmaster. Syloxi (read, silicon or the French silicium) is a metalloid, meaning it may look like a metal, but it is not. It is so named for a Rolex patented silicon geometry allowing for optimized isochronism and enhanced chronometric regularity.
What is the purpose of a flat spring?
Flat springs are commonly used to hold other assembly components together in a specific position and may function as flat springs or electrical conductors. What is a flat spring? Flat springs work like a spring and are small, stamped metal components that are used within small intricate spaces. How do you make a flat spring?
What brands use silicon hair springs?
Silicon hairspring are in used across different Swatch group brands (Breguet, Omega, etc.). The Patek Philippe advanced research department unveiled their Spiromax© hairspring in 2006.
Why choose spring manufacturing corporation?

Is Richemont’s hairsprings production capable?
Although fully operational much later, Richemont has also built production capability for hairsprings. Like Rolex, it was a matter of gaining independence for the watchmaking powerhouse. The production was initiated in Germany with A. Lange & Söhne and Switzerland with Jaeger-LeCoultre. The integration of Roger Dubuis provided another source.
