A Lantis watch that is worn every day will provide many years of precise time keeping as they are built to last.  Lantis watches have moving parts and will require servicing to ensure continued use for many more years.

We recommend to service your Lantis at an approved Lantis watch repair center and to do so every 8 years.

You can help preserve that gorgeous lustre on the polished surfaces by cleaning it from time to time with a soft cloth.  If grime and other residue has built up in the corners of the watch case and metal bracelet, you can wash the case and metal bracelet using soapy water and a soft brush.

If your watch is fitted with a leather watch strap, first remove the leather straps using the quick release before cleaning the case with a soft brush.  Clean the leather watch strap separately.

If you wear your Lantis daily, you don’t need to wind it. If you take it off and set it aside, the watch will retain sufficient power reserve for two days or more, depending on the model.

If you haven’t worn your Lantis for more than a couple of days and the watch has stopped ticking, you can manually wind it up to set the time before putting it back on.  As you start winding the crown, after a few turns, the seconds hand will start moving again.  Give it a few more turns, then set the time.  You can then place the watch back on your wrist.  As you move around, the watch will re-energise automatically.

The Marine Grade 316L Stainless steel case of your Lantis protects it from water ingress and makes it completely dustproof and waterproof.  All Lantis watches are waterproof to at least 100 meters depth.  Some of our Professional collection watches can reach saturation depth of 300 meters, which requires a special mix of oxygen and helium to facilitate breathing as the ocean crushes down on the diver's lungs.  To maintain the watertight integrity of the watch, the case must be properly sealed.

The crown of your Lantis screws down tightly and snugly seals the watch like a submarine's hatch.  After loosening the crown and setting the time, it is essential you ensure you have screwed down the crown nice and firmly.  There is no need to over tighten the crown too tight.  When you feel strong resistance to further tightening, then you will know that it has been sufficiently tightened.  

Magnetic fields are a leading cause of disruption to the watch's accuracy. A few seconds on a demagnetising device at your closest Watch Service Center is sufficient to cancel out ambient fields if you find your watch is not keeping time of +/- 10 seconds per day.

Never expose your watch to extremes of temperature.
Avoid rapid extreme temperature changes.
Avoid excessively hot temperatures above 60ºC /140ºF and avoid cold temperatures -0ºC, or 32ºF.
