Bvlgari Diagono Aluminium 38mm Ref AL38TA Watch

Q: What is the Bvlgari Diagono Aluminium 38mm Ref AL38TA?
A: It’s a vintage, Swiss‑made sports watch with a 38mm aluminium case, a crisp white dial with date, a black rubber bezel engraved “BVLGARI,” and a black rubber/aluminium strap with a pin‑buckle. The aluminium and rubber construction makes it lightweight and comfortable for everyday wear.

Q: What movement does it use and what power reserve should I expect?
A: This reference is automatic (self‑winding). Many examples use a Swiss ETA‑based calibre, though exact calibre can vary by production run. A well‑maintained movement typically offers around 40 hours of power reserve, but real‑world results depend on service history and wear. We can confirm the calibre in this specific watch on request.

Q: Is it water‑resistant and can I swim with it?
A: While the Diagono Aluminium was designed as a sporty watch, water resistance on vintage pieces cannot be guaranteed. We recommend avoiding swimming, showering, or submersion unless the watch has been freshly serviced with new seals and pressure‑tested. Always ensure the crown is fully pushed in before any exposure to moisture.

Q: How do I set the time and date on this automatic watch?
A: If the watch has stopped, wind the crown in the first position (about 20–30 turns). Pull the crown to the next position to quickset the date (if applicable), and to the final position to set the time. Avoid changing the date between roughly 8pm and 2am to protect the mechanism. When finished, push the crown back in securely.

Q: How should I care for the aluminium case and rubber bezel/strap?
A: Wipe surfaces with a soft microfibre cloth. For light cleaning, use lukewarm water with a drop of mild soap, then dry thoroughly. Avoid solvents, alcohol, perfumes, sunscreen, strong detergents, or abrasive pads, as these can mark aluminium and degrade rubber. Store away from heat, UV, and humidity.

Q: Can the strap be resized or replaced, and what wrist size will it fit?
A: This strap secures with a pin‑buckle and fits a wrist up to approximately 19.5cm. Replacement original Bvlgari rubber/aluminium straps are model‑specific; availability varies and they should be sourced via authorised Bvlgari service centres or reputable dealers. If buying aftermarket, ensure compatibility with the Diagono Aluminium 38mm (AL38) fittings.

Q: Will the rubber bezel wear or fade over time, and is it replaceable?
A: Rubber components can show surface wear or fading with age, UV, and chemical exposure. Avoid abrasives and harsh cleaners. Replacement bezels may be available through Bvlgari service, subject to parts availability; we can advise on options if needed.

Q: What crystal does it have—sapphire or acrylic?
A: Most Diagono Aluminium models feature a scratch‑resistant sapphire crystal. Specifics can vary by year and reference; we’re happy to confirm the crystal type on this exact watch upon request.

Q: Is 38mm suitable for my wrist, and is it unisex?
A: 38mm offers a balanced, medium presence that suits many wrists and styles. Although often marketed to men, the Diagono Aluminium’s minimalist design and lightweight build make it popular as a unisex option—fit comes down to personal preference.

Q: What about authenticity, warranty, and what’s included?
A: A Retro Tale professionally authenticates every item and offers a 12‑month mechanical guarantee, free insured DHL shipping, and a 14‑day money‑back guarantee. Please refer to the listing’s Accessories section for what is included—this piece is delivered with no accessories unless otherwise stated.
