Diashock is a shock-resistance device. A device created by Seiko to protect the balance wheel from shock and vibration. The jewel anchoring the balance staff is attached to a hairspring, and when the balance staff is subjected to a strong shock, the elasticity of that hairspring absorbs it.
Invented by Seiko in 1959, the Magic Lever allows all the energy generated by the oscillating weight’s motion to be transferred to the main spring. It is effective, simple and durable and contributes significantly to the longevity of the watch.
Spron mainspring and hairspring alloys are exclusive to Seiko watches. Spron features superior elasticity, strength, and corrosion and heat resistance. The high performance characteristics of the Spron family of alloys have led to its use in a wide range of fields from electronics to medicine.
