To keep your watch performing at its best, we recommend avoiding strong impacts, extreme temperatures, and prolonged exposure to moisture unless your watch is designed for water activities. After exposure to salt water, rinse the watch gently with fresh water and dry with a soft cloth.
For mechanical watches, regular wear helps keep the movement running smoothly. If the watch is not worn often, manual winding may be needed depending on the model. Quartz watches may require battery replacement over time.
Leather straps should be kept away from excessive water and humidity to preserve their appearance and longevity.
Because care recommendations can vary by brand and model, please refer to the manufacturer manual included with your watch for detailed operating instructions, water resistance guidelines, and service intervals.
