Important Notes
While the watch is water resistant to 100 meters, it is not suitable for scuba diving or high-impact water sports. To maintain optimal performance, avoid exposing the watch to strong magnetic fields or extreme temperature changes. The Eco-Drive technology requires periodic exposure to light to maintain full charge—store in a well-lit area when not in use. The package includes the watch on its stainless steel bracelet; no additional straps or accessories are included. Please refer to the manufacturer’s instructions for proper care and maintenance.
