2. Oppsett
2.1 Utpakking og første inspeksjon
Carefully remove the watch from its packaging. Inspect the watch for any visible damage. Ensure all protective films are removed before use.
2.2 Stille inn tiden
- Unscrew the crown (located at the 9 o'clock position) counter-clockwise until it pops out to position 1.
- Pull the crown out further to position 2. The second hand will stop.
- Vri kronen for å stille inn time- og minuttvisere til ønsket tid.
- Push the crown back to position 1 and screw it clockwise firmly against the case to ensure water resistance.
2.3 Angi dato
- Unscrew the crown counter-clockwise until it pops out to position 1.
- Turn the crown clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this may damage the movement.
- Once the date is set, push the crown back to position 1 and screw it clockwise firmly against the case.

2.4 Bracelet Adjustment
The stainless steel bracelet may require adjustment for a comfortable fit. It is recommended to have this procedure performed by a professional jeweler or watchmaker to avoid damaging the links or pins.
3. Bruk av klokken
3.1 Tidtaking
Once set, your NIXON 51-30 Chrono watch will accurately display the time using its Japanese Quartz movement. The large hour and minute hands indicate the current time, while the small sub-dial at the 6 o'clock position typically functions as the running seconds hand for continuous timekeeping.
3.2 Kronograffunksjon
The chronograph function allows for precise timing of events. The watch features two pushers on the left side of the case, above and below the crown.
- Start/stopp: Press the upper pusher to start the chronograph. Press it again to stop.
- Tilbakestille: While the chronograph is stopped, press the lower pusher to reset all chronograph hands to their zero positions.
The sub-dials on the watch face measure elapsed time:
- The sub-dial at the 12 o'clock position measures chronograph minutes.
- The sub-dial at the 6 o'clock position measures chronograph hours (or running seconds, depending on the specific movement configuration).
- The large central second hand functions as the chronograph second hand.

3.3 Vannmotstand
Your NIXON 51-30 Chrono watch is water resistant to 300 meters (30 ATM). This makes it suitable for professional marine activity and serious surface water sports, but not for saturation diving. Always ensure the crown is fully screwed in and the pushers are not operated while the watch is submerged or wet to maintain water resistance.
4. Vedlikehold
4.1 Rengjøring
To clean your watch, wipe the case and bracelet with a soft, damp cloth. For stainless steel, a mild soap solution can be used, followed by rinsing with clean water and drying thoroughly. Avoid using harsh chemicals or abrasive materials.
4.2 Batteribytte
The watch is powered by a nonstandard battery. When the battery runs low, the watch may stop or the second hand may skip. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
4.3 Water Resistance Seal Check
It is recommended to have the water resistance seals checked periodically, especially if the watch is frequently exposed to water or extreme temperature changes. This helps ensure the watch maintains its specified water resistance.
4.4 Oppbevaring
When not in use, store your watch in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields. The original watch box is ideal for storage.
5. Feilsøking
- Klokken går ikke: Check if the crown is fully pushed in and screwed down. If the watch still does not run, the battery may need replacement.
- Feil tid/dato: Refer to Section 2.2 and 2.3 to reset the time and date.
- Chronograph Hands Misaligned: If the chronograph hands do not reset to zero, consult a professional watchmaker for adjustment.
- Vanninntrengning: If moisture appears inside the watch crystal, immediately take the watch to a qualified service center. Do not attempt to open the watch yourself, as this will void the warranty and compromise water resistance.
