Omega Constellation 24mm 2012 Diamond Watch

Q: What are the key features of this Omega Constellation 24mm reference?
A: This 2012 Omega Constellation reference 123.15.24.60.55.005 features a 24 mm stainless steel case and bracelet, a diamond-set bezel, a white mother-of-pearl dial with diamond hour markers, sapphire crystal, and the signature Constellation claws at the sides of the case.

Q: Is this watch quartz or automatic?
A: This model is powered by Omega calibre 1376, which is a precision quartz movement. That means it is battery-powered and chosen for convenient, accurate everyday wear.

Q: Does a quartz Omega need winding or servicing?
A: It does not require daily winding, but it still benefits from regular care. As with any fine watch, battery changes, gasket checks and periodic servicing are important, and Omega also recommends regular water-resistance checks over time.

Q: Are the diamonds and mother-of-pearl dial original to this model?
A: Yes. This reference was produced by Omega with a diamond-set bezel and diamond hour markers on a white mother-of-pearl dial, so these details are part of the model’s original design rather than added decoration.

Q: Will the mother-of-pearl dial look exactly like the photos in every light?
A: Not always. Mother-of-pearl is a natural material, so its iridescence can shift depending on the light and viewing angle. That subtle variation is part of what makes this type of dial so distinctive.

Q: How does the 24 mm size wear, and what is the current bracelet fit?
A: A 24 mm case wears as a refined, compact watch with a jewellery-inspired look on the wrist. For this specific piece, the listed bracelet perimeter is approximately 18 cm, which gives a helpful guide to current fit.

Q: Is this watch water resistant?
A: This reference is commonly listed with 100 metres of water resistance. However, with any pre-owned watch, we recommend treating water exposure with care unless the seals have been recently checked and the watch has passed a pressure test.

Q: What is included with this watch?
A: This watch comes with its box and manual. Everything included with the item is listed in the product information on this page.

Q: Is this reference still available new from Omega?
A: No. Omega lists this reference as no longer available, so it is a discontinued model that is now found on the pre-owned market.

Q: How should I care for the steel, diamonds and dial?
A: To help preserve its condition, wipe the watch gently with a soft cloth and avoid direct contact with solvents, detergents, perfumes and cosmetic products. For long-term upkeep, professional servicing and condition checks are recommended, especially for water resistance and bracelet wear.
