2.1 시간 및 날짜 설정
- 왕관을 빼세요: Gently pull the crown (located on the right side of the watch case) to the second click position.

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 크로노그래프 기능
The chronograph measures elapsed time up to 60 minutes in 1/5-second increments.
- 시작: 위쪽 푸셔(A)를 눌러 크로노그래프를 시작하십시오. 크로노그래프 초침이 움직이기 시작합니다.
- 중지: Press the upper pusher (A) again to stop the chronograph. The elapsed time will be indicated by the chronograph second hand and minute subdial.
- 재설정 : 정지 후 아래쪽 푸셔(B)를 눌러 크로노그래프 바늘을 0 위치로 재설정하십시오.
- 분할 시간: 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 Tachymeter Function
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).
- 읽기 속도: 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. 유지관리 및 관리
4.1 방수성
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 청소
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 배터리 교체
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. 문제 해결
- 시계가 작동하지 않음: 크라운이 완전히 눌려 있는지 확인하세요. 그래도 시계가 작동하지 않으면 배터리를 교체해야 할 수도 있습니다.
- 크로노그래프 바늘이 0으로 재설정되지 않음: This may require a chronograph reset procedure. Consult a professional watchmaker or the detailed movement module manual for specific instructions.
- 날짜는 변경되지 않습니다. Ensure the time is set correctly for AM/PM. If the date changes at noon, the time is set 12 hours off.
