You can swim with all of our SAR™ dive watches, ensuring crown is screwed down securely. Designed for professional Search and Rescue Divers, these watches are submersible up to 30ATM (300m/1000ft). 

We do not recommend swimming with the General Purpose and Pilot’s Navigator watches as they are not meant to be submerged for extended periods but are splash resistant. 

Repairs typically take approximately 6-8 weeks to complete but can take up to 12 weeks depending on parts availability. Upon scheduling your repair or servicing, our team will inform you of the estimated timeline for the return of your watch.

Please visit our Manual page for step-by-step instructions on how to adjust this for your particular model.

First, we recommend checking the health of your clock batteries. The display on some clocks often continues to work even when the battery has become too weak to operate the receiver used to obtain the atomic time signals. 

If you find that the clock still doesn't work after you have replaced the batteries, this issue may be due to local interference that has recently been added close to the clock's location. This may include a new electronic device such as a TV or computer.  Power adapters for these devices can often produce a radiating signal that blocks your clock’s receiver (remember that these adapters/devices may still be on even if they seem to be powered off but are not unplugged). Your clock may need to be re-located further from these devices in order to reduce the amount of interference.  

If you are still unable to synchronize your atomic clock even after replacing the batteries or re-locating it away from other electronic devices, the next step is to temporarily place the clock next to a window when you wish to synchronize the time. We recommend using a window that faces 90 degrees away from the location of the transmitting tower - for example, if WWVB or DCF77 is to the east or west of you, place the clock in a north or south-facing window. Please note that this is better to do at night as there is less external radio interference.  

This is most likely due to your clock being set to the wrong time zone. Please visit our Manual page for step-by-step instructions on how to adjust this for your particular model.

To keep your clock/timer/stopwatch running optimally, we recommend replacing the batteries at least once a year, or at such a time as the clock indicates a replacement is required.
