Q: Is the watch quartz or automatic, and what servicing should I expect?
A: Diagono models in this size and era were often quartz, though some variants were automatic. We can confirm the exact movement in this specific watch on request. As guidance: quartz typically needs a battery every 2–3 years; automatic movements benefit from routine servicing roughly every 5–10 years depending on use and storage.

Q: What are the size and fit details?
A: The case measures 27mm. The supplied strap fits a wrist up to approximately 17cm or smaller. If you’re unsure about fit, share your wrist measurement and we’ll advise sizing options or alternative strap solutions.

Q: Can I replace the strap, and what should I know about caring for crocodile leather?
A: Yes, the strap can be replaced with a correctly sized Bvlgari or high‑quality aftermarket strap; we can confirm lug width and advise options. For care, wipe with a soft, dry microfibre cloth, keep away from water, perfumes and solvents, and store in a cool, dry place away from direct sunlight to prevent drying or cracking.

Q: How do I set the time and date safely?
A: Pull the crown gently to the setting position. For time, turn the hands to the correct hour and minute; for the date, avoid changing it between approximately 8pm and 2am to protect the mechanism. Push the crown back in firmly when finished. If the watch is quartz, there’s no winding step; if automatic and stopped, wind 20–30 turns before setting.

Q: Is it water‑resistant and can I wear it in the rain or swim?
A: Water resistance on vintage watches cannot be guaranteed without recent gasket replacement and pressure testing. Treat it as splash‑resistant at best; avoid swimming, showering or submersion. Always ensure the crown is fully secured before any exposure to moisture and keep the leather strap dry.

Q: What crystal does it use and is the bezel finish durable?
A: Many Diagono models of this era feature a scratch‑resistant sapphire crystal; we can confirm the crystal type on this exact watch upon request. The black case/bezel finish should be treated gently—avoid abrasives, knocks and harsh chemicals to preserve the surface and engraving.

Q: What accuracy should I expect and how should I maintain it?
A: A healthy quartz Diagono should keep excellent daily time; an automatic should keep good time with minor variance depending on age and service history. Keep the watch away from strong magnets, extreme temperatures and moisture, and have it inspected if you notice running fast/slow or any condensation under the crystal.
