2. 初期設定と充電
2.1 初期充電
Your SEIKO Prospex Speedtimer is powered by light energy. Upon receiving your watch, ensure it is exposed to sufficient light to begin charging. A full charge provides approximately 6 months of power reserve. Place the watch in direct sunlight or under strong artificial light for several hours to ensure it is adequately charged before initial use.
2.2 時刻と日付の設定
- リューズを引き出します: リューズを2段目のクリック位置までゆっくりと引き出します。秒針が止まります。
- 時間を設定する： Turn the crown to set the hour and minute hands. Ensure the 24-hour hand is also set correctly (e.g., if it's 3 PM, set the 24-hour hand to 15).
- 日付を設定します。 Push the crown back to the first click position. Turn the crown to adjust the date. Avoid setting the date between 9 PM and 1 AM to prevent damage to the movement.
- リューズを押し込みます: 時刻と日付を設定したら、リューズを通常の位置に戻します。秒針が動き始めます。

3. Operating Your Chronograph
The chronograph function allows for precise time measurement up to 60 minutes in 1/5 second increments.
3.1 クロノグラフの開始と停止
- 上部のプッシャー（A）を押すとクロノグラフがスタートします。クロノグラフの秒針が動き始めます。
- 上部のプッシャー（A）をもう一度押すとクロノグラフが停止します。経過時間はクロノグラフの秒針と分針で表示されます。
3.2 クロノグラフのリセット
- After stopping the chronograph, press the lower pusher (B) to reset it. All chronograph hands will return to their zero positions.
3.3 Tachymeter Function
The tachymeter scale on the bezel can be used to measure speed over a known distance (e.g., 1 kilometer or 1 mile). Start the chronograph at the beginning of the distance. When the unit distance is completed, stop the chronograph. The number on the tachymeter scale indicated by the chronograph second hand is the average speed per hour.
4. お手入れとメンテナンス
4.1 耐水性
Your watch is water resistant to 10 bar (100 meters / 330 feet). This means it is suitable for swimming and snorkeling, but not for scuba diving. Always ensure the crown is pushed in completely before exposing the watch to water.
4.2 クリーニング
Wipe the watch case and bracelet regularly with a soft, dry cloth to remove dirt and moisture. For stubborn dirt, use a soft brush with mild soap and water, then rinse thoroughly and dry. Avoid using harsh chemicals or abrasive materials.
4.3 クリスタルケア
The watch features a curved sapphire crystal with an anti-reflective coating on the inner surface. Sapphire is highly scratch-resistant but not entirely scratch-proof. Avoid impacts and contact with hard surfaces to maintain its pristine condition.
4.4 LumiBrite
The hands and markers are coated with LumiBrite, a luminous paint that absorbs light energy and emits it in the dark. For optimal glow, expose the watch to bright light for a few minutes before entering a dark environment.

5。 トラブルシューティング
5.1 Watch Not Running or Stopping
- 充電不足: Ensure the watch is exposed to sufficient light for several hours to fully charge the solar cell.
- クラウンの位置: Check that the crown is pushed in completely to the normal position.
5.2 クロノグラフ針がゼロにリセットされない
- リセット手順: Ensure you are following the correct reset procedure (press the lower pusher B after stopping the chronograph). If hands are misaligned, refer to the detailed manual for specific calibration steps.
5.3 日付が正しく変更されない
- タイムゾーン調整: Ensure the time is set correctly, especially the AM/PM distinction, as this affects the date change.
- 手動調整: If the date is stuck, manually advance the date using the crown (first click position) until it is correct.
