Inspired by London's most famous clock face, these exclusive cufflinks house a fully functioning quartz watch with Japanese movement and comes with a one year warranty. Grey printed numerals on a white face allow you to tell the time with each Big Ben frame finished on a highly polished stainless steel casing. The face of each cufflink measures 19mm length x 19mm height x 8mm width. We recommend that customers remove jewellery before going to bed or participating in any physical activity. Exposure to certain harsh chemicals or environments will result in compromising the integrity of your jewellery. Including but is not limited to the following: perspiration, perfumes, cleaning agents, chlorine, saltwater, and silver polish. Please keep jewellery made from different materials separated from each other to avoid damage, tarnishing and colour changes over time. To clean, use a solution of warm water and dish soap and allow the jewellery to soak for around 10 minutes. You can use your fingers to rub any marks away gently and then rinse the jewellery in clean lukewarm water. To dry, gently pat the jewellery with a 100% cotton towel. Be sure to rinse the jewellery thoroughly to avoid unpleasant residue and not leave the jewellery in the water solution for longer than 15 minutes. All Tateossian battery-operated mechanical products should only be fitted with batteries from reputable jewellers, watch specialists or Tateossian retailers.
