A: The Quadrella is known for its compact, jewellery-inspired look. This example features a stainless steel case and bracelet, a white dial with coloured gemstone hour markers, and diamond-set claws.

Q: Is this watch quartz or automatic?
A: This reference uses an Omega quartz movement, so it does not need manual winding and is designed for easy everyday timekeeping.

Q: What size is this watch?
A: The listed case diameter for this piece is 20 mm. It wears as a small, refined mini watch, ideal if you prefer a neat and elegant wrist presence.

Q: What wrist size will it fit?
A: It currently fits a wrist of 16.5 cm or smaller and comes with 2 extra links. If needed, a watchmaker can adjust the bracelet for the best fit.

Q: What is the condition of this watch?

Q: What is included with the watch?
A: This watch comes with product information including the box, certificate, booklet and outer box.

Q: Is the crystal sapphire?
A: Yes. This reference is fitted with a scratch-resistant sapphire crystal, which offers better everyday durability than standard mineral glass, although no crystal is completely scratch-proof.

Q: Can I swim or shower with it?
A: This reference was originally rated to 30 metres of water resistance. However, with any vintage or pre-owned watch, it is safest to treat it as splash-resistant unless it has been recently pressure tested, so swimming, showering and soaking are best avoided.

Q: How often will the battery need changing?
A: Omega lists a battery life of around 48 months for this quartz reference, although actual lifespan can vary. If the seconds hand starts moving in 4-second jumps, the battery should be replaced promptly.

Q: Does it need servicing?
A: Quartz watches are generally low-maintenance, but regular checks are still important. Omega recommends checking water resistance yearly and arranging a complete service roughly every 5 to 8 years depending on wear and use.
