Q: Will the bracelet fit my wrist, and can it be resized?
A: The bracelet fits up to approximately 17cm as currently configured. We can size the bracelet before shipping by adding/removing links. Extra links for Constellation bracelets can often be sourced subject to availability and may incur a fee—contact us with your wrist measurement for guidance.

Q: Is the bracelet integrated, and can I swap it for a strap?

Q: What movement does it use and what battery life should I expect?
A: The watch is powered by a Swiss quartz movement for precise, low‑maintenance timekeeping. Typical battery life is around 2–3 years depending on use and storage. The exact battery type can vary by movement—please have a professional watchmaker confirm and replace the cell to protect the seals and finish.

Q: Is it water‑resistant and can I swim with it?
A: Vintage and pre‑owned watches should be treated as splash‑resistant unless they’ve been recently re‑sealed and pressure‑tested. We recommend avoiding swimming, showering and submersion. If light water resistance is important, have the gaskets checked and the watch pressure‑tested by a qualified watchmaker.

Q: Does this model have a sapphire crystal and diamond hour markers?
A: Most Constellation variants from this era feature a scratch‑resistant sapphire crystal. This example has a black dial with diamond hour markers. Exact diamond specifications (cut/carat) are typically modest for hour markers; we can confirm details where available.

Q: How do I set the time on this quartz Constellation?
A: Gently pull the crown out to the setting position and rotate to set the time; then push the crown back in to start the movement. If your specific Constellation variant includes a date, avoid changing the date between approximately 8pm and 2am to protect the mechanism.
