Q: How does the FESTINA F6695 watch measure water temperature?

The diving watch FESTINA F6695 is equipped with a built-in temperature sensor that automatically measures the water temperature during your dives and even in time/calendar mode. During the dive: The water temperature is automatically measured and displayed from the start of the dive, alongside depth and duration. To display the temperature at any time during the dive, simply press and hold button (A) to replace the duration display with the temperature value. In time/calendar mode: Press and hold button (A) for 2 seconds or more to activate temperature measurement. Measurements are then taken and displayed every 10 seconds for 3 minutes , with a resolution of 0.1°C (very accurate). Measurement range: The temperature is measurable from -5.0°C to +40°C (23°F to 140°F). Outside this range, the display remains empty. Accuracy: Accuracy varies depending on the temperature range: ± 2°C between +15°C and +40°C , and ± 3°C between -5°C and +14°C . The depth gauge operates optimally within a guaranteed temperature range of 10°C to 40°C . Logbook recording: The minimum temperature of each dive is automatically recorded in the dive log (capable of storing 4 dives). If an error message “ER” appears instead of the depth, it indicates that the temperature measurement is erroneous at that moment.
