Заведення механізму
Your Longines L2.673.4.78.6 is an automatic mechanical watch. Before setting the time, ensure it has sufficient power reserve. To manually wind the watch, unscrew the crown (if applicable) and turn it clockwise approximately 30-40 times. The watch will also wind automatically with wrist movement.
Встановлення часу та дати
- Щоб встановити час, pull the crown out to position 3 (farthest out). Turn the crown to set the hour and minute hands. The seconds hand may stop, allowing for precise time setting.
- Щоб встановити дата, pull the crown out to position 2. Turn the crown clockwise or counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM to prevent damage to the movement.
- After setting, push the crown back to position 1 (closed) and screw it in securely to ensure water resistance.
Регулювання браслета
For optimal comfort and security, the metal bracelet should fit snugly but not too tightly. Bracelet adjustment typically requires specialized tools and should be performed by a qualified watchmaker or an authorized Longines service center.

Догляд та обслуговування
прибирання
To maintain the appearance of your watch, clean the case and metal bracelet regularly with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, ensuring the crown is fully screwed down. Rinse with clean water and dry thoroughly. Avoid using harsh chemicals.
Вказівки щодо водонепроникності
Your Longines L2.673.4.78.6 watch has a specific water resistance rating. Refer to the case back for the exact rating (e.g., 30m, 50m, 100m). Ensure the crown is always fully pushed in and screwed down before any contact with water. Water resistance is not a permanent characteristic and may decrease over time due to aging gaskets or accidental impacts. It is recommended to have the water resistance checked annually by an authorized service center.
Регулярне обслуговування
Like any precision instrument, your mechanical watch requires periodic servicing to ensure its accuracy and longevity. Longines recommends a complete service every 3 to 5 years, depending on usage and environmental conditions. This service includes cleaning, lubrication, and adjustment of the movement, as well as replacement of worn components and gaskets.
Зберігання
When not wearing your watch, store it in a dry, cool place, away from direct sunlight, extreme temperatures, and strong magnetic fields. If storing for an extended period, consider a watch winder to keep the automatic movement running.
Усунення несправностей
- Годинник не працює: If the watch stops, manually wind it by turning the crown clockwise 30-40 times. If it still does not run, it may require servicing.
- Неточність часу: Slight variations in timekeeping are normal for mechanical watches. If the watch is consistently gaining or losing significant time, it may need adjustment or servicing.
- Стрілки хронографа не скидаються до нуля: If the chronograph hands do not return precisely to zero after pressing the reset pusher, the movement may require adjustment by a qualified watchmaker.
- Condensation Under Crystal: The presence of condensation under the crystal indicates a loss of water resistance. Immediately take the watch to an authorized service center to prevent further damage to the movement.
