Q: What type of crystal does the Diagono Aluminum use? A: Many Diagono Aluminium models are fitted with a scratch‑resistant sapphire crystal. We’re happy to verify the crystal type on this exact reference for you on request.
Q: Will it fit my wrist, and can the strap be resized? A: This watch fits a wrist up to approximately 21cm as listed. The integrated rubber strap with aluminium links can typically be adjusted by repositioning/removing link modules or at the clasp. Share your wrist measurement and we’ll advise or size it prior to dispatch; sourcing extra link elements may be possible subject to availability.
Q: Can the rubber bezel or strap be replaced? A: Yes—replacement rubber components should be fitted by an authorised Bvlgari service centre or experienced specialist to ensure correct fit and sealing. Availability can vary by reference and production period; some third‑party parts may not fit properly. Contact us if you’d like help sourcing genuine components.

Delivery & Returns
Q: What is the Bvlgari Diagono Aluminum 40mm Ref. BB40AT? A: It’s a Swiss‑made luxury sports watch featuring a 40mm aluminium case, a distinctive black rubber bezel with BVLGARI engraving, a black dial with date, and an integrated black rubber strap with aluminium links. It uses an automatic movement and blends technical practicality with bold Italian design.
Q: What are the key materials and design features of this model? A: The case is aluminium for lightness, paired with a black rubber bezel and an integrated rubber strap that includes aluminium link elements. The dial is black with a date display, and the overall aesthetic is contemporary and sporty while remaining refined for everyday and evening wear.
Q: Which movement does it use and what power reserve should I expect? A: It houses a Swiss automatic movement (often ETA‑based in this model family). Typical power reserve for comparable automatic calibres is around 38–42 hours. We can confirm the exact calibre in this specific watch on request.
Q: Is it water‑resistant and can I swim with it? A: As a pre‑owned/vintage piece, water resistance cannot be guaranteed without recent servicing and pressure testing. Treat it as splash‑resistant at best and avoid swimming or showering unless the gaskets have been replaced and the watch has been professionally tested. Always keep the crown fully secured/pushed in before any exposure to moisture.
Q: How do I set the time and date safely? A: If the crown is screw‑down, first unscrew it anti‑clockwise; otherwise, gently pull it out. Position 1: wind the watch (about 20–30 turns if it has stopped). Position 2: quickset the date (if your movement supports it). Position 3: set the time. Avoid changing the date between roughly 8pm and 2am to protect the mechanism. When finished, push the crown in (and screw it down if applicable).
Q: What type of crystal does the Diagono Aluminum use? A: Many Diagono Aluminium models are fitted with a scratch‑resistant sapphire crystal. We’re happy to verify the crystal type on this exact reference for you on request.
Q: How should I care for the aluminium case and rubber components? A: Wipe surfaces with a soft, dry microfibre cloth. Avoid abrasive polishes, solvents, perfumes, sunscreens and saltwater, which can mark rubber and encourage oxidation/pitting on aluminium. Store away from high heat and humidity. If moisture resistance matters, have seals inspected periodically. Light wear and patina on aluminium and rubber are normal for this model family.
Q: Will it fit my wrist, and can the strap be resized? A: This watch fits a wrist up to approximately 21cm as listed. The integrated rubber strap with aluminium links can typically be adjusted by repositioning/removing link modules or at the clasp. Share your wrist measurement and we’ll advise or size it prior to dispatch; sourcing extra link elements may be possible subject to availability.
Q: Can the rubber bezel or strap be replaced? A: Yes—replacement rubber components should be fitted by an authorised Bvlgari service centre or experienced specialist to ensure correct fit and sealing. Availability can vary by reference and production period; some third‑party parts may not fit properly. Contact us if you’d like help sourcing genuine components.
Q: What accuracy and servicing interval should I expect? A: A healthy Swiss automatic should keep good time, though performance varies with age and service history. A routine service about every 5–10 years is typical, or sooner if you notice issues (running fast/slow, moisture). Keep the watch away from strong magnets and wipe it clean after wear.
Q: What is included, and do you guarantee authenticity and provide a warranty? A: This listing is delivered with box as stated. A Retro Tale rigorously authenticates every item and guarantees 100% originality. All watches include a 12‑month mechanical guarantee. We offer free, fully insured DHL shipping, a 14‑day return policy, and 0% customs fees for EU buyers; please contact us for any specific delivery or warranty questions.
