Frequently Asked Questions - Big Bang Unico Magic Gold 411.CM.1138.RX HUBLOT
How do I wind the watch manually?
Unscrew the crown to position 1 (pulled out fully for setting). Turn clockwise about 20-30 times until you feel resistance. This fully winds the mainspring. Screw the crown back down to ensure water resistance.
How do I set the date?
Pull the crown out to position 2 (first click). Turn clockwise to advance the date. Avoid setting date between 9 PM and 3 AM as the date mechanism is engaged. Screw crown back after adjustment.
How do I use the chronograph?
Press the top pusher (start/stop) to begin timing; press again to stop. Press the bottom pusher to reset all counters to zero. Do not operate pushers under water.
Is the watch water-resistant for swimming?
Yes, it is rated to 10 ATM (100 meters), suitable for swimming and snorkeling. However, do not operate pushers under water. After salt water exposure, rinse with fresh water.
How do I adjust the rubber strap?
The strap has a deployant buckle with micro-adjustment holes. Open the buckle, move the pin to the desired hole for fit. Ensure the pin is securely fastened.
Can I replace the battery myself?
No, this watch uses an automatic movement that does not require a battery. It is powered by your wrist motion. For any repair, visit an authorized Hublot service center.
How often should I service the watch?
Hublot recommends a full service every 3 to 5 years to maintain accuracy and water resistance. This includes cleaning, lubrication, and seal replacement.
What is 'Magic Gold' material?
Magic Gold is an 18K gold-ceramic composite developed by Hublot. It is highly scratch-resistant (9 on Mohs scale) yet retains the luster of gold.
How do I clean the ceramic bezel?
Wipe the bezel with a soft, damp cloth. Avoid abrasive cleaners. Ceramic is scratch-resistant, but can chip on hard impact.
What is the power reserve and how do I check it?
The power reserve is 72 hours. There is no indicator; if the watch stops, wind it manually about 20 turns to restart.
