Omega Constellation 34mm 1998 Watch

Q: What is the Omega Constellation 34mm (1998) ref. K25110521069?
A: It’s a vintage, Swiss‑made Omega Constellation in stainless steel with a 34mm case, grey dial with a date display, and a fixed bezel engraved with Roman numerals. Understated and refined, it suits business to evening wear and offers a classic mid‑size presence that many consider unisex.

Q: Is the movement quartz or automatic, and what are the power/accuracy expectations?
A: Late‑1990s Constellations were produced in both quartz and automatic variants. We can confirm the exact movement in this specific piece on request. As a guide, quartz models typically run to seconds per month and need a battery every ~2–4 years; automatic models are self‑winding with a typical power reserve around 38–48 hours and accuracy of seconds per day depending on service history.

Q: How do I set the time and date safely?
A: Gently pull the crown to the first click to set the date (if quickset) and the second click to set the time. Avoid changing the date between roughly 8pm and 2am to protect the mechanism. If the watch is automatic and has stopped, give it 20–40 turns of the crown to start it, then wear regularly. If it’s quartz, no winding is required. If you’re unsure of the crown positions on this piece, contact us and we’ll guide you.

Q: Is it water‑resistant and can I swim with it?
A: As a vintage watch, water resistance cannot be guaranteed without recent servicing and pressure testing. We recommend avoiding swimming, showering or submersion. Keep the crown fully pushed in, and have gaskets inspected and replaced if light moisture resistance is desired.

Q: Will the bracelet fit my wrist, and can it be resized or swapped for a strap?
A: This watch fits a wrist up to approximately 17.5 cm as listed. The bracelet can usually be resized by adding/removing links; extra links may be sourced subject to availability. The Constellation’s integrated design means strap swaps require correctly fitted end links—contact us for compatible options and sizing assistance.

Q: What crystal and bezel does it use?
A: Most late‑1990s Constellations feature a scratch‑resistant sapphire crystal; we can confirm the crystal type on this exact piece if you wish. The bezel is fixed (non‑rotating) with engraved Roman numerals. Clean with a soft, dry microfibre cloth and avoid abrasive polishes that could soften edges over time.

Q: How does the 34mm size wear, and is it suitable for men or women?
A: 34mm offers a classic, vintage‑proportion look that suits small to medium wrists and those who prefer a discreet, elegant presence. It’s commonly worn unisex—fit ultimately comes down to personal style and wrist shape.

Q: What is the condition of this watch?
A: Overall very good vintage condition with small scratches from use. The hardware is shiny with surface scratches on the case and bracelet. Please review the photos for the most accurate impression—vintage pieces naturally show signs of their story and wear.

Q: What’s included in the sale?
A: This listing is delivered with no accessories unless stated otherwise on the page. If you would like advice on storage pouches or travel cases, we’re happy to recommend suitable options.

Q: Is it authentic, and what warranty, shipping and returns do you offer?
A: A Retro Tale rigorously authenticates every item and we own all watches we list. All watches come with a 12‑month mechanical guarantee. We offer free, fully insured DHL shipping, a 14‑day return policy, and 0% customs fees for EU buyers. We can also help confirm the reference, serial and production year (this piece dates to 1998) and share additional photos or details on request.

Q: How often should I service it and how do I care for it day‑to‑day?
A: Typical service intervals are every 5–10 years (or sooner if accuracy or water‑resistance concerns arise). Keep the watch away from strong magnets and extreme temperatures, wipe it with a soft microfibre cloth after wear, and have gaskets checked periodically. If quartz, replace the battery promptly when low; if automatic, regular wear helps maintain performance.
