With our in-house movement factory and service center, we ensure our watches meet the highest quality standards and are built to last. However, if any manufacturing related faults occur, all watches enjoy a two (2) year international warranty(a). Just send us the watch and we will get it sorted.

  • (a) Shipping to the service center to be borne by the buyer. All other costs related to repairing non man-made damages and return shipping are included in the two (2) year international warranty from the original date of purchase.


  • Avoid wearing the watch when playing sports that could have a “violent” vibration on the movement (such as golf, tennis etc). 

  • The power of the mechanical watch is driven by the mainspring barrel.  This self-winding mechanical watch is equipped with a self-winding mechanism, so it is highly recommended to wear it or manually wind it regularly.  

  • The energy will be stored to make the watch function well. If the watch is not worn or wound for a certain period of time, the time accuracy of the movement will be affected, the watch will stop working when the energy is fully utilized.  In order to maintain the accuracy of the time measurement, it is highly recommended that customers should wear it or wind it regularly, or place the watch inside the self-winding winder to wind it. After being worn for a whole day, the self-winding movement will stop for around 40 hours. (For more information, please refer to the “Winding Up Your Watch”).  Make sure that the crown has been pushed back completely in the case before any contact with water.  

  • Do not pull the crown when the watch is immersed in water.  

  • Keep the watch away from all sources of heat and electro-magnetic fields of all kinds.  

  • Keep the watch away from high heat or environments with corrosive gases.  

  • Human sweat and perfume are among the most common types of corrosive catalysts and should be removed using a soft fabric cloth (e.g. silk) immediately.


  • LORESUM watches are high-precision, high-technology manufacture products. Before leaving the workshops, your watch has undergone a series of standardized quality tests and rigorous inspections. Our quality control system ensures that your watch has achieved its intended performance before it reaches your hand. An international warranty covers your watch for any manufacturing defects for a period of two (2) years from the date of purchase. This warranty is valid in LORESUM watch service centers, subject to the following conditions: 

  • The watch has been purchased from the exclusive LORESUM watch authorized retailer; the date of purchase and reference for the watch are clearly marked on the warranty card. 

  • Your watch has been worn under the normal conditions of use and maintenance recommended by LORESUM watch and has not been mishandled. The warranty card is the only valid proof of purchase.  It should be provided to the authorized LORESUM watch service center when repair service is required.
