Safety Information

Safety Instructions for Sailing Race Watches (Optimum Time and Ronstan)
Rules for Safe Use
Proper Use and Operation

Use the watch only for its intended purpose, i.e., for measuring time during sailing activities.
Carefully read the user manual provided with the watch to fully utilize its features such as start countdown, regatta mode, and alarms.
When using the watch in water conditions, ensure it is properly secured on your wrist or mounted in the designated place.
Protection Against Damage

Avoid exposing the watch to excessive vibrations or impacts, which could damage its mechanism or screen.
Do not use chemicals, detergents, or solvents to clean the watch, as they may damage the case or straps.
Regular Inspection Before Use
Water Resistance:
Before use, check if all seals are in good condition, especially if the watch has been serviced or used intensively.
Functionality:
Ensure that the buttons function properly and that the LCD screen displays readable data.
Battery:
Regularly check the battery level. Ensure that the battery is properly charged or replaced to prevent failure at a crucial moment.
Cleaning and Maintenance
After each use in seawater, rinse the watch with fresh water to remove salt, which can weaken seals or damage the mechanism.
Store the watch in a dry, cool place, avoiding prolonged exposure to direct sunlight, which could affect the quality of the materials.
Emergency Situations
If the seals or mechanism are damaged, do not use the watch until it is serviced by an authorized provider.
If the watch stops working during use, plan an alternative time measurement method to ensure safety on the water.
Ensure that alarm and countdown functions are working properly before starting the regatta or voyage.
Additional Tips
Optimum Time and Ronstan offer different models of race watches. Choose a model that suits your needs and the sailing environment (e.g., models with larger displays for easier reading in difficult conditions).
Regular servicing at authorized points guarantees long-lasting and reliable use of the watch.
Contact in Case of Issues
If you notice a manufacturing defect or damage, contact the manufacturer or point of sale. Do not modify the watch yourself in ways that may affect its performance.
