SONY and MURATA
Where did the Sony button cells go?
In 2017, Murata acquired Sony's battery and accumulator division and took over manufacturing of the Sony brand.
Since then, the Murata brand has replaced the Sony brand, but the quality and performance of the batteries remain unchanged.
Quality: no changes
The batteries now carry the Murata brand but continue to be manufactured in the same factories, by the same production teams who still follow the same strict quality procedures.
Performance: no changes
Murata's mercury-free high-performance button cell batteries are globally recognised by leading watch movement manufacturers, covering approximately 45% of global demand.
MURATA: The World's No. 1 Producer
- • Inventor of the mercury-free silver oxide watch battery
- • Renowned supplier to global movement manufacturers
- • Over 40 years of manufacturing experience
- • Over 1 billion watch batteries produced
Namely: Murata batteries combine perfectly with Miyota movements.
