Why do we use sapphire crystal?

Sapphire crystal is the third-hardest transparent material in the world – after diamond and moissanite. In a wristwatch, sapphire crystal is known above all for its resistance to both scratching and breakage. Unlike sapphire crystal, mineral glass is not scratch-resistant.


Why are the crowns, pushers and backs all secured with screws?

Screw-down crowns and pushers cannot become loose due to shocks or getting caught and thus prevent moisture from entering the movement. Particularly when playing sports or doing hard physical work, an unscrewed crown or pusher can become loose and cause damage to the movement or the wearer’s clothing. The back of the case is not simply pressed on, but also secured with screws, which means the back cannot be unevenly pressed on and seals more effectively. Moreover, it cannot be loosened by shocks.


Why are the links of the strap secured with screws?

The links of a watch strap are often connected by small pins, which are held in position by pressure. However, they can become loose over time due to shocks and strain on the strap. Screws, on the other hand, are far more sturdy and can be retightened at any time. You can also secure the screws with a little thread lock.


Why is the ABYSS model equipped with a ceramic bezel?

Fixed bezels, such as those of our MONACO and LEMANS models, are mostly made of stainless steel. Revolving bezels are often made of aluminium. The revolving bezel of the ABYSS, however, is made of ceramics, which is scratch-resistant, unlike aluminium. On the other hand, a ceramic bezel is far more complicated to manufacture – and therefore more expensive. The ceramic bezel is manufactured in colours in an elaborate process. That’s why you will mostly find ceramic bezels only in the premium segment.


What is a tachymeter?

With a tachymeter you can measure speeds in units per hour over a specified distance. The average speed is usually measured in km/h. You can read the value on your tachymeter after one kilometre, but you can also specify other units. Apart from speeds in km/h, it can also measure flow rates in litres per hour, for example.


What does water-resistant mean?

For us, water-resistant means you don’t have to worry about damaging your MIYEN in water. Although many watches are declared water-resistant, in our opinion a watch is only really water-resistant from 10 ATM. You can find an indication of what the different ATMs mean in the user manual of your MIYEN.

All MIYEN watches are water-resistant up to a minimum depth of 100 metres and the ABYSS diver’s model even up to 200 metres.


What is the difference between Japanese movements and those of other manufacturers?

Just like Japanese cars, Japanese movements have a reputation for excellence and reliability. However, they are very good value for money. Watches featuring Japanese movements are often referred to as “premium” in our price segment.


What is the difference between an automatic and a quartz movement?

A watch equipped with an automatic movement is wound up by the movement of your hand. If the watch is not worn for several consecutive days, the so-called power reserve runs out and the watch stops working. If your watch is fully wound, it has a power reserve of around 40 hours. A quartz watch, on the other hand, is powered by a battery and does not need winding. The accuracy of a mechanical automatic watch is, of course, not comparable with that of a quartz watch. Minor deviations of 30 seconds either way per day are normal, particularly when temperatures differ. All MIYEN automatic movements are accurate within 10 seconds either way per day. 

Which characteristics does every MIYEN typically have?

All MIYEN watches have a red second hand. We simply liked the idea of departing from the usual format. Moreover, the red feature makes the watch look sportier. Apart from the red second hand, you will also find the engraved coordinates of our hometown on every MIYEN. Tradition meets modernity.
