FAQs
What is King Gold?
King Gold is an exclusive 18K gold alloy developed by Hublot. It contains platinum, giving it a warmer hue than traditional 5N 18K gold and enhancing its polishing and finishing qualities.
What is the Unico 2 caliber?
The Unico 2 caliber is a compact, in-house automatic chronograph movement designed by Hublot. It features a visible double coupling system and a 72-hour power reserve, optimized for smaller case sizes like the 44mm Big Bang.
How long does the power reserve last?
The Unico 2 caliber provides a power reserve of approximately 72 hours, meaning it can keep accurate time for three days even when not being worn.
Is the watch suitable for swimming or diving?
The water resistance rating varies by specific model and its intended use. Always check the case back or product specifications for the exact water resistance (e.g., 50m, 100m). For diving, a watch specifically rated for high depths is required.
How do I clean my Hublot watch?
Clean the watch with a soft, dry microfiber cloth. For more thorough cleaning, use a slightly damp cloth and dry immediately. Avoid using soaps, solvents, or abrasive cleaners.
What is the typical servicing interval for this watch?
Mechanical watches, especially those with complex movements like the Unico 2, typically require servicing every 3 to 5 years to maintain accuracy and ensure the longevity of internal components.
Can the strap be easily changed?
Hublot's Big Bang models often feature an interchangeable strap system, allowing for customization. Consult your watch manual or a Hublot boutique for strap compatibility and changing instructions.
Troubleshooting
Watch has stopped running
Manually wind the crown clockwise until resistance is felt. If the watch is not worn regularly, ensure it is wound sufficiently. If the issue persists, it may require servicing.
Chronograph function is not engaging or resetting correctly
Ensure the crown is pushed fully into its normal position. If the problem continues, the chronograph mechanism may require adjustment by a qualified watchmaker.
Difficulty setting the time or date
Gently pull the crown to the appropriate position for setting the time or date. Avoid forcing the crown. If it feels stiff, do not proceed and consult a watch professional.
Scratches on the King Gold case or bracelet
Minor scratches can sometimes be buffed out during professional servicing. Avoid activities that could lead to significant impacts or abrasive contact.

Setup, Compatibility & Care
Setup:
This timepiece is a mechanical watch and does not require initial digital setup. To begin using, wind the crown clockwise until you feel resistance, or simply wear it to activate the automatic winding rotor. Set the time by pulling the crown to the desired position and turning it.
Compatibility:
As a watch, its primary compatibility is with the wearer's wrist. The included strap is designed for comfort and durability, typically made from materials like rubber, which are hypoallergenic and resilient. Ensure the strap buckle is fastened securely.
Care:
- Cleaning: Clean the case and bracelet regularly with a soft, dry microfiber cloth. For stubborn smudges or marks, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive materials.
- Water Resistance: Refer to the specific water resistance rating for your model (often indicated on the case back). Avoid exposing the watch to water or steam beyond its rated limit, especially in hot water or saunas, as this can damage seals.
- Winding: If the watch stops, wind the crown manually until resistance is felt. If worn daily, the automatic movement should maintain the power reserve. Avoid overwinding.
- Servicing: Mechanical watches like the Big Bang require periodic servicing (typically every 3-5 years) by a certified watchmaker to ensure optimal performance and longevity of the Unico 2 movement. This includes cleaning, lubrication, and seal replacement.
