FAQ

Luminox Light Technology (LLT) uses tiny, self-powered micro gas light tubes housed in borosilicate glass capsules. These tubes are installed in the hands, hour markers or dial, and, where applicable, the bezel. They provide a constant glow for up to 25 years, with a 10-year illumination guarantee from the date of purchase, provided the watch is not subjected to strong shocks.

Unlike conventional luminous paint, LLT does not require an external light source to charge and does not need to be activated by pressing a button. The light tubes are safe for humans and the environment and do not consume battery power.

Quartz movement:
The typical tolerance of a quartz movement is between -0.5 and +0.7 seconds per day. External factors such as shocks or sudden changes in temperature may affect its accuracy.

Mechanical movement:
Accuracy depends on the movement and the wearer's habits and may vary. The average precision tolerances is between -10 and +40 seconds per day.

Luminox watches have a water-resistance rating of 100–500 metres, depending on the model, as indicated on the case back.

This rating is based on laboratory pressure testing and does not mean that the watch will remain water resistant indefinitely. Please note that temperature differences and external influences such as solvents, cosmetics, dust and shocks such as impact or sudden movement can significantly affect the water resistance. It is possible for the crown or crystal to be jarred without leaving a visible mark, but this can damage the movement and reduce water resistance.

It is also important to note that seals and sealing systems are affected by wear and aging. This applies, for example, to the sealing rings around the glass, around the crown and the case back.

Not all straps or bracelets are suitable for use in water. The crown and pushers should never be operated underwater, and any screw-down crown must be firmly secured before exposure to water. After use in water, especially salt water, rinse the watch with clean, fresh water, then clean and dry it thoroughly.

Do not under any circumstances open the watch yourself. We recommend having the water resistance tested at least once a year by an authorised Luminox service centre, particularly if the watch is frequently exposed to water.

We recommend the following waterproof ratings for specific activities in or near water:

• Splash water: 3 ATM / 30 metres
• Water surface activities: 5 ATM / 50 metres
• Swimming / snorkelling: 10 ATM / 100 metres
• Diving: 20 ATM / 200 metres (we recommend a screw-threaded crown)
• Deep sea diving: specific ISO 6425 tests required

Specially constructed Luminox dive watches, such as the 1500 Series, undergo more rigorous testing according to ISO 6425.

Luminox watches are manufactured in a clean room with controlled humidity of 45% to help prevent condensation. However, under certain circumstances condensation may occasionally form inside the watch due to natural humidity. This can happen when it is exposed to sudden changes in temperature, such as moving from hot sunlight into cold water or a cold shower.

In normal circumstances, the fog should disappear within a few minutes once the watch returns to room temperature. If the condensation does not disappear after 2–3 minutes, please send the watch to an authorized Luminox service centre. Persistent fogging may indicate damaged or aged gaskets or other issues that could affect the watch's water resistance.

Like any high-precision instrument, your watch should be serviced regularly to ensure optimal performance. As a general guideline, we recommend a full service every 3 to 4 years, depending on how frequently the watch is used, as well as factors such as the model, climate, and care taken by the owner.

Battery life typically ranges from 2 to 10 years, depending on the watch model, dimensions, battery capacity, the size and weight of hands, and the energy required by the movement and its functions. For example, a chronograph generally consumes more energy than a watch displaying only the hours and minutes.

Some Luminox watches feature an end-of-life indicator. When the second hand begins moving in 4-second intervals, it is time to have the battery replaced by a Luminox-qualified watchmaker. The watch will typically continue to run for approximately 1 to 3 weeks after the indicator begins. Please note that the battery is not covered under the original warranty.

The materials used by Luminox are carefully tested to help minimise the risk of allergic reactions. If you are sensitive to stainless steel, we recommend choosing a Luminox watch made with titanium or plastic.

Luminox uses calf leather for its leather straps.

Depending on use and wear, leather and PU straps typically last between 6 and 18 months. As straps are exposed to sweat, bacteria, dirt, water, sunlight, and other environmental factors, regular replacement is recommended for both hygiene and durability. We recommend replacing your strap at least every 18 months.

A tachymeter measures the approximate speed of a moving object or person over a defined distance.

To use it:

• Start the chronograph when the object or person begins moving.
• Stop the chronograph once the object or person has completed the defined distance.

The information you will find can be read as follows:

1. The object or person needed x seconds to complete the known distance
2. The tachymeter calculates and shows the speed of the object or person.
