Do my glasses come with a case?

What are the lenses made of?

Our polarized lenses are made from Tri Acetate Cellulose film (TAC film).

It’s a chemical compound produced from cellulose and a source of acetate esters, typically acetic anhydride. Tri Acetate is commonly used for the creation of fibres and film base and it’s chemically similar to cellulose acetate.

Tri Acetate Cellulose (TAC) polarized lenses feature a new lens technology formulated for superior visual and polarization clarity. They have a scratch coating, reduce glare and eye strain, while still delivering 100% UVA/B/C protection and blocking 100% harmful UV rays up to 400 nanometers. These lenses are very lightweight and highly impact resistant.

Does sea water damage my glasses?
Our Polaroid TAC UV400 lenses are not and cannot be immersed in sea water.

Are your sunglasses water-proof?
Wooden glasses can’t be soaked in water for a long time. If your glasses get wet, dry them as soon as possible.

How resistant are wooden glasses?

Wooden glasses resist small falls, but can suffer if they fall from high altitudes,. Please don’t try to fold them, because bamboo and wooden sunglasses are not as flexible as plastic materials.
You can add these points to the instructions for use. If the above problems occur or the buyer maliciously damages the product because it does not want the product, we will not be responsible for this after-sales problem or refund the buyer.


Can I replace the battery?

For Diania wood watches that utilize a quartz movement, a battery replacement may eventually be needed. The Diania repair team will gladly replace your battery. Simply complete an RMA request and one of our repair specialists will get back with you quickly to let you know the costs and timeline associated with replacing your battery. You may also visit a reputable jeweler or watch repair shop and have the battery replaced. We do not suggest that Diania watch owners attempt to change the battery themselves.

Are the watches made of real wood?

Yes, they are! We use natural wood recycled scraps sourced from major wood dealers. Each wood type has its own unique colors, patterns and grain, making each Diania watch one-of-a-kind.

Are Diania watches water resistant?

All Diania watches are considered to be splash proof, some of them are water resistant (3 ATM). Normal wear and use can include kitchen activities, a day on the beach, the gym, etc. However, full submergence in water is not recommended both for the integrity of the movement and the wood itself. Excessive moisture exposure can result in a diminished flexibility in the band’s wood links. If this occurs, allow the watch to dry for 1 to 2 days to allow the wood links to dry and return to their natural size.

How can I care for my watch to prevent cracking and increase durability?

With proper care, your wood watch can be worn for many years to come.

The biggest enemy of wood is sudden changes in temperature and humidity. This means if you leave your watch in a car on a hot sunny day, the high temperature has the ability to swell the wood and cause it to crack. Same with leaving it in the car on a particularly cold day or night, the cold will shrink the wood, putting pressure against the glass and pins and could cause breakage at those points.

Humidity control is also important. Too much and the wood will absorb the water and swell, too little and it will dry out the wood and shrink. Swelling and shrinking increase the possibility of cracking at the time and in the future.

SO, when you are not wearing your watch be sure that it is inside, and also protected in either its original packaging OR in a watch or jewelry box to protect it from an overly wet or dry environment.

Additionally, the best thing you can do for the wood of your watch is make sure it is properly conditioned, protecting the wood from the elements. We recommend Tung Oil or Lemon oil both of which can be found at hardware stores, or online.

Using a soft cloth, pour 1 teaspoon of your chosen oil onto the cloth and then use the cloth over the surface of the wood, buffing slightly. This will aid in keeping your watch clean and conditioned and will increase the luster.

How can I adjust the wood watch to fit my wrist?

Take your Diania watch to your preferred jeweler or watch repair shop to have them size it for you.

How do I wind my automatic wood watch?

Upon receiving your wood watch, be sure to note the instruction card provided. Wind the watch at least 15-20 times prior to wearing it. After the initial winding, your daily activity should be sufficient to keep the watch wound, IF worn every day for a minimum of 8 hours.

Lack of sufficient movement or inconsistent wearing of the watch may require additional manual winding. As this is a mechanical watch, quartz watch accuracy cannot be expected. If your watch is consistently fast or slow regardless of proper winding and wearing, and you have surpassed the warranty period, we recommend taking your watch to a reputable jeweler or watch repair store and having them service the watch which should include: cleaning, oiling, and regulating the movement.

How does the one year warranty work?
