The mb-microtec Ltd.’s customer service ensures the perfect maintenance of your traser® watch. If your watch needs attention, rely on an official traser® dealer or an authorised traser® service center listed on the website ( They can guarantee service according to mb-microtec Ltd.’s standards.

Replacing the battery 

We recommend that you contact an approved traser® service center or an authorised traser® retailer, as they are equipped with the tools and apparatus required to carry out the work and the necessary checks in a professional manner. A worn-out battery should be replaced immediately in order to reduce the risk of leakage and consequent damage to the movement. 

trigalight® self-powered illumination

trigalight® consists of hermetically sealed systems, which function entirely without the need for external light or energy sources. Moreover, you can read the time reliably and without having to push a button or any other kind of handling. The trigalight® illumination technology has a lifespan of at least 12 years. However, the intensity of the trigalight® will fade over the years due to radioactive decay. Additionally, minor differences in the brightness of the individual trigalight® components may occur as a result of the production process. A standard traser® watch contains a maximum activity of 1 gigabecquerel (GBq) of tritium gas. The exceptions are marked with T100, indicating the activity concentration of 3.7 GBq. Tritium is a radioactive element found in trace amounts in nature and which can also be man-made. The gaseous tritium is sealed in a small hollow body of mineral glass. The tritium atom decays into helium by emitting a beta particle (electron). Your watch is not giving off any harmful radiation since the electrons are unable to pass through either the mineral glass or the watch’s case. 

The trigalight® components are installed in accordance with internationally applicable requirements and will not break nor release tritium gas under the expected mechanical and thermal loads. All watches containing trigalight® need to comply with internationally applicable test requirements and guidelines ISO 9978 and ANSI/HPS N43.4-2005. traser® watches comply with all of these standards and have been approved by the Swiss Federal Office of Public Health under the number «A-211764-59».

Precautions and Preventive Measurements

Do not expose your watch to sudden temperature changes (e.g. exposure to sunlight followed by immersion in cold water) or extreme temperatures [over 60°C (140°F) or below 0°C (32°F)]. 

Magnetic fields 
Do not expose your watch to intense magnetic fields such as loudspeakers, mobile phones, computers or refrigerators and other electromagnetic appliances. 

Avoid impacts, drops, and repeated friction that could abrade the metal and affect the watch mechanism.
In the event of a violent shock please have your watch checked by an authorised traser® service center. 

Harmful products 
Avoid direct contact with solvents, detergents, perfumes, cosmetic products or other chemical products, since they may damage the bracelet, the case or the gaskets. 

Care and checks 
Clean the case and bracelet regularly using a soft cloth to prevent any corrosion caused by perspiration. All water resistant watches can be cleaned with a toothbrush and soapy water, and then dried with a soft cloth. After being worn in the sea, the watch must be rinsed with warm fresh water and then dried completely.

Water resistance 
Water resistance of watches is rated based on laboratory pressure tests comparable to a swimmer or diver sitting still at that pressure level. However, many water-based activities involve a lot of movement and other environmental changes. These exceptions to how the watch was rated may challenge or defeat the water protection features of a water resistant watch. 

The water resistance of a watch cannot permanently be guaranteed. It may be affected by ageing of gaskets or by accidental shock to the crown. We recommend that you have the water resistance of your watch checked once a year by an authorised traser® service center. 

Never activate the time-setting crown and/or the pushers while the watch is under water and make sure that the crown has been pushed/ screwed down tightly after every operation. Do not under any circumstances open the watch yourself; arrange to get it inspected by an authorised traser® service center only. All traser® watches are water-resistant at least to 3 atm/bar (30m/100ft). More information available on the PDF download.

traser® finishings

Galvanic coatings 
These coatings are applied by electrolysis. By varying the timing and current intensity, it is possible to vary the thickness and nature of the different layers (e.g. gold, silver, copper, etc.). 

PVD (physical vapour deposition) coating 
This process is performed under vacuum. Microscopic particles are deposited on the products by ion bombing. Very thin layers (1 to 3 µm) of impurity-free components can be made, which possess a high level of hardness (nitride, carbides, etc.). PVD has the advantage of being a thin but hard layer, corrosion-resistant, with strong adhesion and providing a numerous choice of colours. Thanks to the inert nature of PVD, the risks of intolerance entailed by its use are minimised. 

Titanium is a metallic element found in the Earth’s crust. Hardened titanium is 30% tougher but around 40% lighter than steel, and is 100% recyclable. Thanks to the biocompatible nature of titanium, the risks of intolerance entailed by its use are minimised. When exposed to the atmosphere, titanium forms an oxide film that makes titanium resistant to salt water and human perspiration corrosion. 

Sapphire glass 
Sapphire is manufactured from aluminium oxide (Al2O3). Transparent and colourless, it can only be scratched or cut with a diamond. Due to its extreme hardness, sapphire is virtually immune to deterioration or distortion, scratch-proof and resistant to wear and chemical attack. Highly polished, sapphire is perfectly transparent. 

Mineral glass (K1)
Mineral glass is hardened by a tempering process and is coated in a hard material, which makes it less likely to be scratched.

Alloy typically made out of 88% copper and 12% tin. Bronze only oxidises superficially. Once an oxide layer is formed, the underlying metal is protected from further corrosion. The outer layer of oxidation can be cleaned to restore its original state. Cleaning instrunctions can be downloaded on our website (

Leather is a durable and flexible material created by tanning animal rawhides. Leather provides a high resistance against tearing, flexing and puncturing. We do not recommend immersing a leather strap in water to avoid erosion and fast-aging of the material.

Silicone is a polymer, which exhibits many useful characteristics such as thermal stability between -148°F to 482°F (-100°C to 250°C), a low chemical reactivity, resistance to ultra-violet light and prevents microbiological growth.

Natural material exhibiting high resilience, elasticity and is extremely waterproof.

Stainless steel 316L 
For the manufacture of all accessible components of its steel watches, traser® has selected a very high quality stainless steel from the 316L family. The advantages of this steel are its high corrosion resistance and excellent durability. 

Like any precision instrument, a watch must be serviced regularly for optimum operation. As a general rule, we recommend that you have your watch checked every 3 to 4 years by your official traser® retailer or service center. However, please note that depending on the climate and the conditions of use of the watch, a shorter interval may be required. To benefit from the highest standards of service and to ensure your guarantee remains in force, please always contact an official traser® retailer or service center.
