What is Bolex?
Bolex is a Swiss camera manufacturer that has been producing mechanical 16mm film cameras since 1927.

The Spring Motor Principle
Bolex cameras work without electricity – a Swiss watchwork mechanism drives the film:
How it Works
- Winding – Side crank tensions the spring (8 full turns)
- Run Time – 28 seconds @ 24 fps per wind
- Speed – 8–64 fps adjustable
- Single Frame – Frame-by-frame exposure possible
Advantages
- Independence – No electricity, no batteries
- Silent – No motor, only spring sound
- Reliable – Mechanics last for decades
- Creative – Time-lapse, slow-motion, animation
