- biranje: The watch face, featuring hour markers (including "12", "9", "6" numerals), hands (hour, minute, second), and the date display at the 3 o'clock position.

- narukvica: The two-tone stainless steel band with a fold-over clasp for secure wearing.
Initial Setup
Navijanje sata
Your Longines Hydroconquest is an automatic watch, meaning it is powered by the motion of your wrist. However, if the watch has stopped or has not been worn for an extended period, it may require manual winding.
- Odvrnite krunicu okretanjem u smjeru suprotnom od kazaljke na satu dok ne izađe u položaj 1.
- Turn the crown clockwise approximately 30-40 times. This will manually wind the mainspring.
- Push the crown back in and screw it down clockwise to ensure water resistance.
Podešavanje vremena i datuma
- Odvrnite krunicu okretanjem u smjeru suprotnom od kazaljke na satu dok ne izađe u položaj 1.
- Gently pull the crown out to position 2 (first click) to set the date. Turn the crown clockwise or counter-clockwise until the correct date is displayed. Avoid setting the date between 9 PM and 3 AM to prevent damage to the movement.
- Pull the crown out further to position 3 (second click) to set the time. The second hand will stop. Turn the crown to move the hour and minute hands to the desired time. To ensure accuracy, synchronize with a reliable time source.
- Once the time and date are set, push the crown back into position 1 and screw it down clockwise firmly against the case to maintain water resistance.
Upravljanje satom
Korištenje jednosmjerno rotirajućeg okvira
The Hydroconquest features a uni-directional rotating bezel, primarily used for timing elapsed periods, such as dive times.
- Align the zero marker (triangle) on the bezel with the minute hand at the start of the event you wish to time.
- Kako vrijeme prolazi, minutna kazaljka će pokazivati proteklo vrijeme na skali okvira.
- The uni-directional rotation prevents accidental movement that would indicate a shorter elapsed time, a critical safety feature for divers.
Otpornost na vodu
Your Longines Hydroconquest watch is water-resistant to 30 bar (300 meters / 1000 feet). This makes it suitable for professional marine activity and serious surface water sports, but not for saturation diving.
- Uvijek se uvjerite da je krunica potpuno zavrnuta prije nego što sat izložite vodi.
- Do not operate the crown or pushers (if present on other models) while the watch is submerged or wet.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly with a soft cloth.
Njega i održavanje
Čišćenje
To maintain the appearance of your watch, clean it regularly.
- Koristite meku, damp cloth to wipe the case and bracelet. For stubborn dirt, a mild soap solution can be used, followed by rinsing with fresh water (only if the crown is fully screwed down).
- Temeljno osušite sat mekom krpom koja ne ostavlja dlačice.
- Izbjegavajte upotrebu jakih hemikalija, rastvarača ili abrazivnih sredstava za čišćenje.
Service and Inspection
For optimal performance and to maintain water resistance, it is recommended to have your watch inspected and serviced by an authorized Longines service center every 3-5 years. This includes checking gaskets, lubricating moving parts, and ensuring timekeeping accuracy.
Skladištenje
Kada ne nosite sat, čuvajte ga na hladnom i suhom mjestu, dalje od direktne sunčeve svjetlosti i jakih magnetskih polja.
