What is the difference between an automatic watch and a mechanical watch?
The difference between an automatic watch and a mechanical watch lies in how they operate. A mechanical watch must be wound manually by turning the crown, usually every day or every two days, to keep functioning. In contrast, an automatic watch winds itself through the movements of the wrist when you wear it.
What is a mechanical watch?
A mechanical watch is a traditional timepiece that operates without a battery or electronic power source. It is driven by a complex mechanism made up of gears, springs, and cogs.
Main Features :
- Manual movement: A mechanical watch must be wound regularly using the crown to continue functioning. This process winds the mainspring, which then releases its energy to power the mechanism.
- Artisanal precision: Mechanical watches are often handmade, reflecting exceptional watchmaking craftsmanship.
- Power reserve: Generally, most mechanical watches have a power reserve of 24 to 48 hours. This means they need to be wound every day or every other day.
What is an automatic watch?
An automatic watch, also known as a self-winding watch, is a specific type of mechanical watch. It uses the natural movement of the wrist to wind itself, thereby eliminating the need for regular manual winding.
Main Features :
- Automatic mechanism: Thanks to a semi-circular rotor integrated into the movement, the watch captures the energy generated by wrist movements. This rotor turns and automatically winds the mainspring.
- Manual winding possible: Most automatic watches also allow for manual winding via the crown, providing an additional option if they are not worn regularly.
- Power reserve : Similar to mechanical watches, with a power reserve often ranging between 40 and 70 hours depending on the model.
The key differences between a mechanical watch and an automatic watch
| Criteria | Mechanical watch | Automatic watch |
|---|
| Reassembly | Manual only (via the crown) | Automatic (wrist movements) and manual possible |
| Practicality | Requires regular winding | Practical for everyday use |
| Complexity of the mechanism | Easier in its construction | Includes a rotor for automatic winding |
| Recommended use | Ideal for lovers of tradition and simplicity | Ideal for those who wear their watch daily. |
| Cost | Often more affordable than automatic watches | Often more expensive due to the complexity of the mechanism |
Advantages and disadvantages
Mechanical watch:
Benefits :
- Reflects a traditional watchmaking know-how.
- Design often finer and more refined thanks to a simpler mechanism.
- Less expensive than automatic watches in certain ranges.
Disadvantages:
- Requires regular manual winding.
- Less practical for daily use, especially for those who forget to wind their watch.
Automatic watch:
Benefits :
- Automatically retracts when lifted, offering better convenience.
- Ideal for mechanical watch enthusiasts but looking for simplified maintenance.
- Advanced technology combining tradition and innovation.
Disadvantages:
- Can stop if not worn for several days (requiring manual winding or the use of a watch winder).
- Often more expensive due to the complexity of the mechanism.
How to choose between a mechanical watch and an automatic watch?
The choice mainly depends on your preferences and your lifestyle:
- If you love authenticity and the ritual of winding, a classic mechanical watch is ideal.
- If you are looking for a functional and practical watch for everyday use, choose an automatic watch.
- If you own several watches : A mechanical watch can be a good complement if you already have automatic models.
The main difference between a mechanical watch and an automatic watch lies in their winding method. While the mechanical watch requires regular manual winding, the automatic watch uses the movements of the wrist to wind itself. Both types embody watchmaking craftsmanship and offer a unique experience to their owners.
Whether you choose a mechanical or automatic watch, you are investing in a timeless piece that reflects tradition, elegance, and precision.
What is a mechanical watch?
A mechanical watch is a timepiece that operates thanks to a mainspring and a complex mechanism of gears. It must be wound manually by turning the crown to maintain its operation.
What is an automatic watch?
An automatic watch is a type of mechanical watch that winds itself thanks to the movements of the wrist. It uses a rotor that turns with natural movements to wind the mainspring, thus avoiding the need for regular manual winding.
Do I need to wind an automatic watch?
Not necessarily, as long as you wear it regularly. If it remains still for several days, it will stop and will require manual winding or the use of a watch winder to resume its operation.
What is the power reserve duration of an automatic or mechanical watch?
The power reserve (the time during which a watch operates after being wound) generally varies between 24 and 70 hours, depending on the model and mechanism. Modern watches tend to offer longer power reserves.
Which watch is easier to maintain: automatic or mechanical?
Both require similar maintenance, such as servicing every 3 to 5 years. However, an automatic watch is more practical for daily use as it winds itself, unlike a mechanical watch which must be wound manually.
