BOSS Chronograph Quartz Watch - Champion Collection - 1513848

To set the time, pull the crown to the furthest position and rotate. To set the date, pull the crown to the first click position and rotate. Push the crown back in completely after setting both.

Yes, with 10ATM water resistance, this watch is suitable for recreational swimming, snorkeling, surfing, and sailing. However, we advise against wearing it in the shower or sauna, as hot water and steam can compromise the water-resistant seals. Always ensure the crown is fully pushed in before water exposure.

10 ATM (Atmospheres) or 100 meters (330 feet) water resistance means the watch is protected from water splashes, rain, and can withstand recreational swimming and snorkeling. It is not designed for diving, especially scuba diving, where greater pressure resistance is needed.

Use a soft, lint-free cloth to wipe away dirt. For deeper cleaning, lightly dampen a cloth with mild, non-abrasive soap and gently wipe the bracelet, then immediately dry it thoroughly with another clean, soft cloth. Avoid harsh chemicals or abrasive cleaners.

This watch features a durable mineral crystal window, which offers good resistance against everyday scratches and impacts.

The battery life of a quartz watch typically ranges from 2 to 4 years, depending on usage. We recommend having the battery replaced by a professional watchmaker to ensure proper installation and resealing for water resistance.

First, ensure the crown is fully pushed in. If it's pushed in and the watch still isn't running, the battery may need replacement. Contact a qualified watchmaker for a battery service.

This often requires a manual adjustment. Pull the crown out to the furthest position. Then, press the chronograph pushers (usually the top and bottom ones) repeatedly or hold them down to cycle the chronograph hands back to the zero position. Refer to the detailed instruction manual if this does not work, as specific models can vary.

Ensure the watch's internal AM/PM setting is correct. To correct this, advance the time past 12 PM (noon) and then past 12 AM (midnight) to see if the date changes. If not, you may have set the date during the 'forbidden' period (9 PM - 3 AM). Adjust the time outside this period, then reset the date.

This indicates a breach in the watch's water resistance seal. Immediately take the watch to a professional watch repair service to prevent further damage to the movement. Avoid trying to dry it yourself.
