Welcome, Eterna enthusiasts! Have you ever found yourself marveling at your exquisitely crafted Eterna watch, only to realize that you’re unsure about the proper winding technique? Worry not, because today’s blog post is here to guide you through the delicate intricacies of winding an Eterna watch with precision and care, ensuring its longevity and enhancing its already mesmerizing allure.

 

How to Wind an Eterna Watch Correctly: A Simplified Guide

Identifying Your Watch Type

Eterna has a remarkable range of watches, from hand-wound and self-winding models to quartz options. While most of their collection focuses on self-winding watches, they also offer quartz models for those who prioritize accuracy with minimal maintenance. 

 

The Kontiki collection, in particular, offers a variety of styles and designs, so there’s truly an Eterna for everyone.

 

Before winding your watch, it’s essential to know its type. Eterna manual-wind watches need regular winding to maintain their power, while self-winding models stay wound through natural wrist movement or by using a watch winder.

 

1. Wearing the Watch Daily

When you wear your Eterna watch frequently, your arm’s natural movement winds the watch’s movement, ensuring accurate timekeeping without manual winding.

 

2. Manual Winding – Rotating the Crown

To manually wind your watch, set the crown to position 0, and wind it clockwise 20 to 30 times. This initial winding will activate the movement, which can then continue to self-wind as you move throughout the day.

 

Note: Some models have a screw-down crown. Be sure to unscrew it fully before winding, and once you’re finished, screw it back in to maintain the watch’s water resistance.

 

3. Automatic Winding – Using an Eterna Watch Winder

If you own multiple luxury watches or don’t wear your Eterna daily, a watch winder can be a practical solution. Reputable brands like Mozsly and Wolf make winders that mimic wrist motion, keeping your watch wound without the need for manual winding.

 

How Does an Automatic Watch Winder Work?

Not familiar with a watch winder? Think of it as a jewelry box with a motor that gently rotates your watch at intervals, simulating the wrist’s natural motion. This keeps your watch fully wound, accurate, and ready to wear.

 

Watch winders offer multiple rotation settings—clockwise, counterclockwise, or both—depending on your watch’s specific needs. If you own more than one watch, a multi-watch winder with alternating rotations is a convenient way to keep them all wound.

 

For Eterna watches, which usually require 650 to 800 turns per day (typically in a clockwise direction), most high-quality winders have the settings needed to keep your timepiece in perfect condition.

How to Properly Use and Set the Eterna Watch Winder?

If for some reason you don’t have access to your watch’s user guide, here are some more detailed tips to help you set up the Eterna watch with your automatic watch winder:

Step 1: Manual Wind First

Since your winder will not wind a watch that is completely stopped, start by turning the crown 20 to 30 times to manually wind the Eterna.

 

Step 2: Secure the Watch in the Winder

Carefully place the watch into the winder, making sure it is fully seated in the holder. Then adjust the TPD to the lowest setting and select bidirectional rotation mode.

 

Step 3: Turn it on & Adjust Settings

Turn on the winder. During the next 48 hours or so, periodically check that the watch is still keeping accurate time. 

Generally speaking, an automatic watch has about 40 hours of reserve time since it is wound. Here’s what to do depending on your situation:

• If Time is Accurate After 2 Days: You’ve found the right setting! Your watch is good to go, and there’s no need to adjust further.
• If Time is Incorrect: Increase the Turns Per Day (TPD) setting to the next level, reset the winder, and let it run for another 48 hours.
• Still Wrong? Try Clockwise Only: If the watch is still losing or gaining time, set the winder to rotate clockwise only. After another two days, check again.
• Last resort – Counterclockwise Only: If the time is still off, switch the setting to counterclockwise only and monitor again for two days.

 

Does Eterna Recommend using a Watch Winder?

Eterna has not explicitly stated whether it recommends the use of watch winders.

 

Although not endorsed, many professional watchmakers agree that the use of a reliable watch winder from a reputable watch winder brand (e.g. Wolf, Mozsly, Barrington) can effectively wind an Eterna automatically. The correct TPD setting is essential to avoid over-winding the movement.

 

So, to summarize – regular wear is the best option, but a quality watch winder can provide a convenient solution for in-between wearing.

 

What is the Best Watch Winder for Eterna?

If you are considering a watch winder, it is vital that you choose a high quality that meets the specific requirements of your Eterna watch. 

Here are two recommended options:

MOZSLY® Single Watch Winder – Black Leather

Material: Wooden Box, PU Leather, Acrylic Board

Dimensions: 4.4 x 6 x 4.4 inche

Features: 4 modes with TPD settings from 650 to 1500, multiple winding directions, upgraded Japanese Mabuchi Motor, anti-magnetization design, dual power type, 3-year warranty, 100% handmade

MOZSLY® Double Watch Winder -Orange Leather

Material: Wooden Box, PU Leather, Acrylic Board

Size: 8.8 x 5.9 x 4.7 inches

Features: Supports two watches simultaneously, quiet motor, adjustable settings, upgraded Mabuchi motor, and 3-year warranty

 

MOZSLY watch winders use high-quality upgraded Japanese Mabuchi motors, a well-known brand that manufactures precision motors. These motors keep the noise below 10 db so it will give you a very quiet experience even if you put it in your bedroom. The internal motor is closed and can be separated from the watch so that the Eterna will not be magnetized and affect the running time.

 

Mozsly watch winders come with a 36-month warranty and friendly customer support, making it easy to buy with confidence!

 

In Conclusion

Choosing a Mozsly watch winder is a smart choice for Eterna owners who want to preserve the accuracy and longevity of their timepieces.

 

Just make sure to select the right TPD and rotation settings, following Eterna’s guidelines for best results. With a Mozsly winder, you’ll enjoy the elegance of your Eterna, always ticking perfectly, year after year.
