Q: What is the Bvlgari Aluminium Steve Aoki 40mm Ref BB40AT?
A: It’s a Swiss‑made automatic wristwatch featuring a lightweight 40mm aluminium case, black rubber bezel with BVLGARI logo engraving, and a distinctive white dial with luminous hands/markers and Steve Aoki’s logo. It pairs contemporary design with Bvlgari’s luxury watchmaking and is water‑resistant to 100 metres.

Q: How does the Steve Aoki edition differ from the standard Bvlgari Aluminium?
A: The Steve Aoki collaboration highlights a specially designed luminous white dial that showcases the DJ’s logo when charged under light. Case, bezel and strap architecture remain faithful to the Bvlgari Aluminium line, delivering the same sporty, modern aesthetic with an artistic twist.

Q: Which movement does it use and what is the power reserve?
A: This model uses an automatic (self‑winding) Swiss movement. Typical power reserve for the Bvlgari Aluminium family is around 40–42 hours, depending on the exact calibre and condition. We’re happy to confirm the movement details in this specific watch on request.

Q: Is it water‑resistant and suitable for swimming?
A: It is rated to 100 metres when new. As a pre‑owned watch, water resistance cannot be guaranteed without recent gasket replacement and pressure testing. Avoid swimming or showering unless it has been freshly tested; always ensure the crown is fully pushed in before any exposure to moisture.

Q: Does the dial glow in the dark and how do I charge it?
A: Yes—the white dial and logo feature luminous material. Charge it by exposing the watch to bright light (natural or artificial) for a few minutes; the glow will be strongest immediately after charging and will fade over time. Performance varies with light intensity and duration.

Q: What materials are used and how should I care for them?
A: The case is aluminium (lightweight but softer than steel), with a black rubber bezel and strap. Wipe with a soft, dry microfibre cloth; for the rubber strap, a light rinse in lukewarm water and mild soap is fine—avoid solvents, perfumes, oils and abrasive cleaners. Aluminium can show light scuffs; avoid polishing compounds that may mark the surface.

Q: What type of crystal does it have?
A: Most modern Bvlgari Aluminium models use a scratch‑resistant sapphire crystal. If you’d like us to verify the crystal on this exact watch, please contact us and we’ll confirm.

Q: Will it fit my wrist, and can the strap be resized or replaced?
A: This watch fits a wrist up to approximately 20 cm. The black rubber strap uses a pin buckle with standard hole adjustments. Strap replacements should be genuine Bvlgari Aluminium components for proper fit; aftermarket straps may not mount correctly due to the model’s specific design.

Q: How do I wind and set the time on the automatic movement?
A: If the watch has stopped, wind the crown (in the pushed‑in position) about 20–30 turns to start it. Pull the crown out to the time‑setting position and turn the hands to the correct time, then push the crown back in firmly. This edition is typically time‑only (no date), making setup straightforward.

Q: What accuracy and service interval should I expect?
A: A healthy automatic movement should keep good daily time; performance varies with age and service history. A routine service every 5–10 years is generally recommended, or sooner if accuracy or water resistance is a concern. Keep the watch away from strong magnets, extreme heat and chemicals, and wipe it clean after wear.
