The movement is the engine inside a watch. It decides how the watch is powered, how accurate it is, how much care it needs — and often, how much it costs.
There are four main types of watch movement you will meet when buying a watch in India: quartz, mechanical (hand-wound), automatic and solar. Two watches can look almost identical from the outside and behave completely differently because of the movement inside. This guide explains how each one works in plain language, compares them side by side, and helps you decide which suits the way you live.
Quick Answer
The Four Types of Watch Movement at a Glance
| Movement | Power Source | Accuracy | Maintenance | Best For |
|---|---|---|---|---|
| Quartz | Battery | Highest | Battery change every few years | Convenience and accuracy |
| Mechanical (hand-wound) | Mainspring wound by turning the crown | Lower than quartz | Daily winding, periodic servicing | Traditional watchmaking |
| Automatic | Mainspring wound by a rotor as you move | Lower than quartz | Regular wear, periodic servicing | Craftsmanship without daily winding |
| Solar | Light, stored in a rechargeable cell | Quartz accuracy | Very low — no routine battery change | Low maintenance |
The Basics
What Is a Watch Movement?
A watch movement, also called a calibre, is the mechanism that measures time and drives the hands and any extra functions — such as the date or a chronograph. Brands give their movements reference numbers. For example, the Seiko Prospex SPB103J1 uses Seiko's calibre 6R35, and the Citizen Tsuyosa uses Citizen's calibre 8210. When you see a calibre number on a product page, it tells you exactly which engine is inside.
Every movement needs three things: a source of energy, a way to regulate that energy into precise, regular beats, and a gear train that turns those beats into the movement of the hands. The four types differ mainly in the first two.
Movement 01
Quartz Movement
How a Quartz Watch Works
A Short History
Seiko released the Quartz Astron 35SQ on Christmas Day 1969 — the world's first mass-produced quartz watch, with roughly 100 times the accuracy of a conventional mechanical movement. Quartz quickly changed the industry because it made accurate watches affordable.
Advantages
- Most accurate type of movement
- Affordable and widely available
- Enables thin and light cases
- Grab-and-go convenience — simply works
Considerations
- Needs a battery change every few years
- Many enthusiasts consider it less "crafted" than a mechanical watch
Movement 02
Mechanical (Hand-Wound) Movement
How a Mechanical Watch Works
Jewels and Power Reserve
Mechanical movements use synthetic rubies — called jewels — at points of high friction to reduce wear. The power reserve is how long the watch runs on a full wind. Most hand-wound watches need winding once a day.
Advantages
- Traditional craftsmanship — no battery ever
- A daily winding ritual many owners enjoy
- Can last generations with proper care
- Smooth sweeping seconds hand
Considerations
- Less accurate than quartz
- Must be wound regularly
- Needs periodic servicing
Movement 03
Automatic Movement
How an Automatic Watch Works
Power Reserve Examples
| Watch | Calibre | Power Reserve | Price |
|---|---|---|---|
| Citizen Tsuyosa NJ0231-56L | 8210 | ~42 hours | ₹49,900 |
| Seiko Presage GMT HCB005J1 | 4R34 | ~41 hours | ₹75,000 |
| Seiko Prospex SPB103J1 | 6R35 | ~70 hours | ₹95,000 |
| Longines Conquest Heritage L16484926 | L896.5 | Up to 72 hours | ₹4,55,000 |
A longer power reserve means the watch keeps running longer once you take it off. A watch with ~70 hours — like the Seiko SPB103J1 — will usually still be running after a full weekend off the wrist.
Advantages
- Mechanical craftsmanship without daily winding
- Smooth sweeping seconds hand
- Often features a see-through caseback
- Self-winding — just wear it regularly
Considerations
- Stops if left unworn beyond its power reserve
- Less accurate than quartz
- Needs periodic servicing every few years
Movement 04
Solar Movement
How a Solar Watch Works
Smart Features
Many solar watches have a low-charge warning — on Citizen Eco-Drive, the seconds hand jumps in two-second steps when the charge is low. Some models have a power-save mode that stops the hands in darkness and moves them back to the correct time when light returns.
Some solar watches go further: Seiko's Astron GPS Solar (first launched 2012) uses satellite signals to set the correct local time automatically.
Advantages
- Quartz-level accuracy
- No routine battery changes — ever
- Very low maintenance overall
- Runs on any light — natural or artificial
Considerations
- Needs regular exposure to light
- The dial must let light through, which can influence dial design

Watch Movements Compared in Detail
| Quartz | Mechanical | Automatic | Solar | |
|---|---|---|---|---|
| Energy | Battery | Hand-wound mainspring | Self-winding mainspring | Light |
| Regulator | Quartz crystal | Balance wheel | Balance wheel | Quartz crystal |
| Seconds hand | Ticks once a second | Sweeps smoothly | Sweeps smoothly | Ticks once a second |
| Accuracy | Highest | Lower | Lower (Citizen 8210: −20 to +40 sec/day) | Highest |
| Stops when | Battery runs out | Not wound | Not worn beyond power reserve | Kept in darkness too long |
| Servicing | Battery change; seals checked | Periodic overhaul | Periodic overhaul | Occasional check |
| Price entry | Widest range | Mid to high | From ₹11,500 (Alba automatic) | Mid range |
The Decision
Which Watch Movement Should You Choose?
You want an accurate watch that simply works, or if you wear several watches in rotation. Quartz is the most reliable daily workhorse — set it, forget it.
You value craftsmanship and will wear the watch most days. An automatic rewards daily wear with smooth performance and is the choice of most serious collectors.
You enjoy the ritual of winding and want the most traditional type of watch. Hand-wound movements connect you directly to the history of horology.
You want quartz accuracy with almost zero maintenance. A Citizen Eco-Drive is an easy, low-maintenance choice that will never let you down.
For a first serious watch, an affordable automatic such as the Alba Automatic AL4185X1 (₹11,500) is a good introduction to mechanical watches, while a Citizen Eco-Drive is an easy, low-maintenance choice.
Caring for Your Watch
How to Care for Each Type of Movement
Replace a dead battery promptly — an old battery can leak and damage the movement. Have the seals checked after every battery change to maintain water resistance.
Wind at the same time each day until you feel resistance, and do not force the crown. Avoid winding the watch while it is on your wrist.
Wear it regularly. If you rotate several watches, consider a watch winder to keep it running between wears.
Keep it in the light. Avoid leaving it in a drawer for months — store it near a window or under indoor lighting to maintain the charge.
For all movement types: keep watches away from strong magnets, and never operate the crown or pushers underwater. Our Watch Care Center offers battery replacement while you wait, water resistance testing and full movement overhauls with genuine parts.
Frequently Asked
Frequently Asked Questions
-
The four main types are quartz (battery-powered), mechanical (hand-wound), automatic (self-winding mechanical) and solar (light-powered quartz). Each has different characteristics in accuracy, maintenance and price.
-
Quartz and solar movements are the most accurate. Seiko says its first quartz watch in 1969 was roughly 100 times more accurate than a conventional mechanical movement. GPS solar watches such as the Seiko Astron also set themselves using satellite signals for perfect timekeeping.
-
Both are mechanical watches using a mainspring and balance wheel. A hand-wound mechanical watch is wound by turning the crown; an automatic watch has a rotor that winds it as you move your wrist. The automatic is more convenient for daily wear.
-
No. Automatic watches are powered by a mainspring wound by your wrist movement — no battery is ever needed. They stop if left unworn beyond their power reserve and simply need to be worn or manually wound to start again.
-
It depends on the model. Citizen says most Eco-Drive watches run for more than six months on a full charge. Store your solar watch near a window rather than in a drawer to keep it topped up.
-
The power reserve is how long a mechanical or automatic watch keeps running on a full wind. For example, the Citizen 8210 runs for about 42 hours and the Seiko 6R35 for about 70 hours. A longer power reserve means the watch survives a weekend off your wrist without stopping.
-
Quartz or solar is best for convenience and accuracy. If you are curious about watchmaking and want to start exploring mechanical watches, an affordable automatic such as the Alba Automatic AL4185X1 (₹11,500) is a rewarding and affordable first step.
There is no single best movement — the right one is the one that fits how you live and what you enjoy.
Quartz gives the best accuracy and convenience. Solar adds near-zero maintenance. Automatic and mechanical watches offer the craftsmanship that makes them special to collectors and enthusiasts alike.
