• Use a soft microfiber cloth to gently remove dust and dirt without damaging the protective layer.
• Place the hygrometer in a dry location to prevent moisture and corrosion, especially in humid environments such as boats or RVs.
• Avoid using aggressive cleaning or polishing agents that could damage the protective coating of the barometer housing.
• Calibrate the hygrometer at the start of the season, after prolonged storage, or if you have any doubts about its accuracy.

• How do I know what size winding key I need?
If your ship's clock has a modern Hermle movement (W0132.071), use the 3.1 mm key. This movement is often used in brands like Schatz, Wempe, Barigo, and Weems & Plath.
• For older mechanical ship clocks you will probably need a key with a larger diameter.
• Please contact our customer service and we will be happy to help you with advice.
• Can I return the winding key if it doesn't fit?
Yes, you can return the key as long as it's unused and in its original condition. However, you'll be responsible for the shipping costs. Contact our customer service for return instructions.
• What if I don't know the key size of my clock?
Don't worry! Contact our customer service and provide us with as much information as possible about your ship's clock (brand, model, or a photo). We'll be happy to help you find the right key.
