Aarni Watches are equipped with high quality and precise Swiss movements (ETA, Ronda) or Japanese Miyota Quartz movements. You can find the specific movement details on product pages. 

We use only high quality sustainable wood. The specific wood type depends on the model and may range from Ebony, Curly Birch and Walnut along many other premium wood materials. The wooden parts are treated lightly with wood treatment oil to maintain natural shine and moisture.

Our watches are assembled at a family-owned factory in Shenzhen, China. As the leading hub of watch manufacturing, Shenzhen offers great possibilities also for our special needs. The choice of factory, responsibility and quality have been very important factors for us from the beginning. We are happy to tell that the working environment and conditions are excellent at the factory. The employees’ working hours are fair and they receive a good remuneration for their efforts. Hence, employment contracts are long and the workers are the best in their field. We also visit the factory on a regular basis.

The Finnish wood material is dried and sawn to blanks in Finland. Most of the movements come direct from the manufacturers in Switzerland and Japan.

Spare parts are available. If you need any additional parts, or any other help, please contact us at info@aarniwood.com and we are happy to help. 

The market leading structure of Aarni Watches guarantees that the movement will be safe from water and dust (5 ATM). You don't have to worry about water accidents in everyday use. Just remember to leave the watch on a table before taking a shower or sauna. 

The battery of quartz movement will last for 2-8 years, after which it is possible to change it yourself or at the nearest watch shop. Wooden parts are treated with natural wood treatment oils, so the wooden parts themselves do not require any special maintenance. However, to retain the wood's natural shine and moisture, we recommend treating the wooden parts with natural wood treatment oil yearly.

We use premium polycarbonate lenses that have great optical properties and they are also very resistant to scratches and shattering. 100% protection against UV radiation comes with the package of course.

Many of our models are also polarized (see specific info on product pages). Polarization eliminates reflections from horizontal surfaces such as water, reducing glare in bright sunshine.

For sunglasses we use only high-quality sustainably grown wood. The wood types we use, depending on sunglasses model include dark walnut wood, zebrawood and ebony for example.

All sunglasses are delivered with a handy cork case to protect your glasses from hits and a microfiber cloth to make cleaning the lenses easy for you. Wooden parts do not require any special care, but to preserve the wood shine and we recommend a treatment with wood treatment oil each year. Please note that long-term exposure to excessive heat may cause dryness and cracking of the wooden parts, so we do not recommend leaving the glasses, for example, in a hot car for a long time.
