2.1 Nastavitev časa in datuma
- Izvlecite krono: Nežno povlecite krono (ki se nahaja na desni strani ohišja ure) do drugega klika.
- Nastavite čas: Rotate the crown to move the hour and minute hands to the desired time. Ensure the 24-hour subdial also reflects the correct AM/PM.
- Nastavite datum: Push the crown back to the first click position. Rotate the crown to adjust the date. Avoid setting the date between 9 PM and 1 AM, as this may interfere with the date change mechanism.

The stainless steel bracelet can be adjusted by removing or adding links to achieve a comfortable fit. It is recommended to have this adjustment performed by a qualified watch technician to prevent damage to the bracelet or watch.
3. Operating the Chronograph and Tachymeter
3.1 Funkcija kronografa
The chronograph measures elapsed time up to 60 minutes in 1/5-second increments.
- Začetek: Pritisnite zgornji potisnik (A), da zaženete kronograf. Sekundarni kazalec kronografa se bo začel premikati.
- Ustavite: Press the upper pusher (A) again to stop the chronograph. The elapsed time will be indicated by the chronograph second hand and minute subdial.
- Ponastaviti: After stopping, press the lower pusher (B) to reset the chronograph hands to their zero positions.
- Vmesni čas: To measure split times, press the lower pusher (B) while the chronograph is running. The chronograph hands will stop to indicate the split time. Press (B) again to resume measurement.
3.2 Funkcija tahometra
The tachymeter bezel allows for the calculation of speed over a known distance (e.g., 1 kilometer or 1 mile) or production rates.
- Start Chronograph: Begin timing an event (e.g., a vehicle traveling 1 unit of distance) by pressing the upper pusher (A).
- Hitrost branja: When the event is completed, stop the chronograph by pressing the upper pusher (A). The position of the chronograph second hand on the tachymeter scale indicates the average speed per hour. For example, if the chronograph second hand points to '120' after 1 unit of distance, the speed is 120 units per hour.
4. Vzdrževanje in nega
4.1 Vodoodpornost
The SEIKO SSB345 watch has a water resistance rating of 10 BAR (100 meters). This means it is suitable for everyday use, swimming, and snorkeling, but not for scuba diving. Ensure the crown is fully pushed in before any contact with water.

4.2 Čiščenje
Wipe the watch case and bracelet periodically with a soft, dry cloth to remove dirt and moisture. For stainless steel bracelets, a soft brush with mild soapy water can be used, followed by thorough rinsing and drying.
4.3 Zamenjava baterije
The watch is powered by a Lithium Ion battery. When the battery life is low, the second hand may move in two-second intervals. Battery replacement should be performed by a professional watchmaker to ensure proper sealing and function.
5. Odpravljanje težav
- Ura ne deluje: Preverite, ali je krona popolnoma potisnjena. Če ura še vedno ne deluje, je morda treba zamenjati baterijo.
- Kazalci kronografa se ne ponastavijo na ničlo: This may require a chronograph reset procedure. Consult a professional watchmaker or the detailed movement module manual for specific instructions.
- Datum se ne spreminja: Ensure the time is set correctly for AM/PM. If the date changes at noon, the time is set 12 hours off.
