Q: Is this an automatic watch?
A: No. This Constellation is powered by Omega’s quartz Calibre 4061, chosen for reliability and slimness. Typical battery life is around 48 months, after which a simple battery change by a qualified watchmaker will bring it back to full running. There is no date function on this 25 mm variant.

Q: What exactly is the blue aventurine dial—stone or glass?
A: It is aventurine glass, crafted to create a starry‑night shimmer. Because of how aventurine glass is made, the speckled pattern and depth of sparkle can vary slightly from piece to piece, making each dial subtly unique.

Q: What are the case and bracelet materials?
A: The watch combines stainless steel with 18‑carat yellow gold. Notable features include the engraved Roman‑numeral bezel in yellow gold, Omega’s signature “claws”, diamond hour markers, and a domed sapphire crystal with anti‑reflective treatment.

Q: What is the size and how does it wear?
A: The case measures 25 mm across and wears elegantly and compact on the wrist thanks to the integrated mono‑rang bracelet and slim quartz movement. It is a refined, jewellery‑style Constellation perfect for smaller wrists or a sleek, minimal look.

Q: Will it fit my wrist and can it be adjusted?
A: This piece currently fits wrists up to approximately 16 cm as listed in the product information. It can be sized down by removing links. To size up, additional Constellation mono‑rang links would be required; these are model‑specific and may need to be sourced separately. The butterfly clasp also offers a small comfort adjustment for fine‑tuning.

Q: Is it water‑resistant and can I swim with it?
A: The model is rated to 3 bar/30 metres. That is suitable for everyday splashes and rain, but we recommend avoiding swimming, showering and saunas. If your watch sees water contact, have its seals pressure‑tested periodically to maintain water resistance.

Q: Is this exact reference still in production?
A: Omega lists reference 131.20.25.60.53.001 as no longer available at retail. This example is from 2022 and offered as a pre‑owned piece in very good condition.

Q: What is included with this watch?
A: The box is included. Everything that comes with the watch is detailed in the product information section on this page; if an item (such as a warranty card or manual) is not listed there, it is not included.

Q: How do you authenticate this watch?
A: Every item at A Retro Tale undergoes rigorous multi‑point checks by our in‑house specialists, including inspection of materials, finishing, engravings, movement, and reference details. We stand behind the authenticity of all pieces and can share additional photos or details on request.
