Omega Constellation 35mm Ref 1502.40 Automatic Watch

Q: What is the Omega Constellation 35mm Ref. 1502.40?
A: It’s a late‑1990s, Swiss‑made automatic Omega Constellation with a 35mm stainless‑steel case and matching integrated bracelet, a grey textured dial, a fixed bezel with Roman numerals, and a date at 3 o’clock. This vintage piece (serial 60253866, circa 1999) is in good condition and suited to refined everyday wear and smarter occasions.

Q: Which movement does it use and what is the power reserve?
A: Constellation automatics from this era typically house an Omega calibre such as the 1120 (based on ETA 2892‑A2) with an approximate 42–44‑hour power reserve. Exact calibre can vary by reference; we can verify the movement in this specific watch on request.

Q: How do I set the time and date on this automatic Constellation?
A: Position 0: crown pushed in (normal running). Position 1: pull the crown out one click to quick‑set the date. Position 2: pull the crown out two clicks to set the time. If the watch has stopped, wind it ~20–30 turns in Position 0 to start it. Avoid changing the date between about 8pm and 2am to protect the mechanism. Push the crown back in firmly when finished.

Q: Is it water‑resistant and can I wear it in the rain or swim with it?
A: Many Constellation models were originally rated around 50–100 metres, but 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, and ensure the crown is fully pushed in before any light moisture exposure.

Q: What type of crystal does this model use?
A: Most 1990s Constellations are fitted with a scratch‑resistant sapphire crystal. If you’d like us to confirm the crystal type on this exact watch, please contact us and we’ll verify it for you.

Q: Will it fit my wrist, and can the bracelet be resized?
A: This watch fits a wrist up to approximately 21cm as listed. The integrated stainless‑steel bracelet can be sized by adding/removing links; additional links may be sourced subject to availability. Share your wrist measurement and we’ll advise sizing options before dispatch.

Q: How do I operate the deployment clasp, and does it have micro‑adjustment?
A: Most Constellation steel bracelets from this era use a folding deployment clasp, often with push‑buttons. Press the side buttons to release; close it until you feel a secure click. Micro‑adjustment is limited; fine fit is usually achieved by link changes rather than on‑the‑fly clasp adjustment.

Q: What condition should I expect from this vintage piece?
A: It is listed in good condition with visible scratches on the case, bezel and bracelet, and shiny hardware with light marks—normal for a well‑kept vintage watch. Please review the photos closely; we’re happy to provide additional images or details upon request.

Q: How does the 35mm Constellation wear on the wrist?
A: The 35mm case offers a classic, mid‑size presence. The integrated bracelet and slim profile make it comfortable on small to medium wrists and refined on larger wrists seeking a vintage‑proportion look. Overall wear is discreet and elegant.

Q: What servicing and care do you recommend?
A: A routine service every 5–10 years is sensible, or sooner if accuracy or water resistance is a concern. Keep the watch away from strong magnets, chemicals and extreme heat, and wipe it with a soft microfibre cloth after wear. Avoid moisture unless the watch has been freshly pressure‑tested.
