Module – Watch Theory (PDF Course)

A Deep Dive into the Function & Operation of the Manual Wind Watch

Gain a clear, structured understanding of the mechanics behind mechanical wristwatches.
Watch Theory is a downloadable PDF course designed to teach the underlying principles that govern the function, interaction, and regulation of parts inside a manually wound mechanical watch.

This course is designed for students taking the Practical or Vocational routes to qualification to MBHI

Know How It Works Before You Open It

Before servicing or restoring a movement, you need to understand its logic.
Watch Theory breaks down each section of a manual wind watch — from mainspring to escapement — explaining how energy flows through the system, how time is regulated, and how precision is maintained.

Perfect for horology students, aspiring watchmakers, collectors, and anyone seeking to truly understand what makes a watch tick.

What the Course Covers

• Energy Flow & Power Delivery
  From the mainspring barrel through the gear train to the escapement — how motion and torque are managed.
• Gear Ratios & Timekeeping
  Understanding wheel trains, reduction ratios, and how they translate into time display.
• Escapement Theory
  Detailed breakdown of lever escapement operation, impulse, locking, and draw.
• Oscillator Function
  How the balance and hairspring regulate time, including amplitude, frequency, and isochronism.
• Setting, Winding & Keyless Work
  How manual winding and time-setting mechanisms interact with the gear train.
• Common Faults & Functional Symptoms
  What theoretical understanding can tell you about practical issues: low amplitude, gain/loss, or stopping.
