General

Does my watch come with a warranty?

Yes, each watch comes with a three-year limited warranty. You can find the details on our website as well as in the owner’s manual that came with your watch.

How do I set the time?

To set the time, simply pull the crown away from the case (until it clicks), rotate the crown either direction to the desired time, then push in the crown (until it clicks again) returning it to its home position against the body of the case.

How long will my battery last?

Your battery will last approximately three years. If it's time to change your battery, we strongly recommend that your battery is replaced here at the Thümm & Co. service center for a nominal fee. If you'd like your battery replaced, send us a note and we will be happy to take care of that for you.

Is my watch water resistant?

This is a little bit of a complicated subject - yes it is water resistant! Your timepiece has been factory tested to a depth of thirty to fifty meters (depending on the model) and and it can safely handle conditions such as rain, perspiration, splashes while washing your hands, etc., but please keep in mind that your watch is not constructed as a diving watch.

The water resistant test is a static laboratory test, which means that the internal watch gaskets are assured to be sealed before we ship the watch to you. This quality assurance process cannot replicate actual use in terms of actual contact a watch can have whilst it is physically submerged or in contact with water. Therefore, we recommend that you exercise caution when it comes to wearing your watch in or around water.

I noticed a haze has formed on the bezel of my R1 model, what do I do?

Oxidation causes a natural haze to form on silver surfaces. If this happens, we recommend two options as solutions to remove oxidation:

Gently wipe the surface of the bezel with a damp, soft cloth to remove the haze.
Mix together a small amount of water and baking soda or toothpaste until it forms into a paste. Then, dip a cotton swab into the mixture and gently rub it on the silver bezel. A heads up; the color of silver tarnish is black color, and is a normal occurrence. Wipe clean with a soft, dampened soft cloth.

Can I polish or clean my watch with the cotton pouch that came with the watch?

We do not recommend using the cotton pouch as a polishing or cleaning cloth. Instead, we suggest using a soft natural cotton cloth (i.e. terry cloth towel) to clean your timepiece.

What happens if I scan the QR code on the caseback of my watch?

When you scan the QR code, you will be sent to an email draft addressed directly to us. From there, you can send us a note or question about your watch. Before you scan the QR code, be sure to wipe the back of the caseback to clean the surface and scan the code in a brightly lit room - for best results, make sure that overhead lighting is not directly shining on the caseback itself.

Where do I find the serial number of my watch?

The serial number is located beneath the QR code in small print on the bottom of the caseback. The serial number is also written on the warranty page in your owner’s manual.

I have an issue with my watch and need it serviced - what do I do?

Please let us know what you need serviced by sending us an email first. Then, we ask that you package your watch securely and mail it to us. We ask that you cover the cost of shipping your watch to our facility.
