An ideal companion for boardroom days and evening occasions, this Omega Seamaster Aqua Terra 38.5mm in steel and 18K rose gold elevates tailored looks.

In excellent condition, circa 2019, it offers refined versatility from day to night.
Please note that the majority of our items are vintage and therefore have tales to tell unless stated otherwise. Therefore, please look at pictures, descriptions and measurements provided as they give you the best idea of the story this item has to tell.
* Please note that when you buy a vintage product, the dimensions may vary slightly from a new one depending on previous care and storage.
Q: What is the Omega Seamaster Aqua Terra 150M 38.5mm (ref. 231.20.39.21.51.003)? A: It’s a Swiss‑made, luxury sport‑elegant watch featuring a 38.5mm stainless‑steel case with an 18k rose‑gold bezel, a black “teak” dial set with diamond hour markers, and a date at 3 o’clock. It’s powered by an automatic Co‑Axial movement visible through a transparent case back and comes on a stainless‑steel bracelet. This example is ca 2019 and is offered as a full set with its original box and certificate.
Q: Which movement does it use and what is the power reserve? A: Aqua Terra models of this reference typically house the Omega Co‑Axial calibre 8500, a chronometer‑grade automatic movement with twin barrels for stable delivery and an approximate 60‑hour power reserve. We can confirm the exact calibre fitted to this piece on request. Expect high‑quality everyday accuracy, subject to age and service history.
Q: Is it water‑resistant and suitable for swimming? A: The Aqua Terra line is rated to 150 metres when new. With pre‑owned watches, water resistance cannot be guaranteed without recent servicing and pressure testing. Avoid swimming, showering or submersion unless the seals have been replaced and the watch has been professionally tested; always ensure the crown is fully pushed in before any exposure to moisture.
Q: How do I set the time and date safely on the Co‑Axial movement? A: Typical setting for the calibre 8500 is: Position 1 (pushed in) for normal wear; pull to the first click to jump the hour hand forwards/backwards in one‑hour steps (crossing midnight changes the date); pull to the second click to set the minutes (and synchronise the hour hand). Avoid changing the date between roughly 8pm and 2am to protect the mechanism, and push the crown fully back in after setting.
Q: What materials and crystal does it feature? A: The case is stainless steel with an 18k rose‑gold bezel, paired with a stainless‑steel bracelet and folding clasp. The dial is black with a horizontal “teak” pattern and diamond hour markers. It is fitted with a scratch‑resistant sapphire crystal (typically anti‑reflective) and a transparent sapphire case back showcasing the movement.
Q: How should I care for the rose‑gold bezel and diamond‑set dial? A: Wipe gently with a soft microfibre cloth after wear. Avoid abrasive polishes, harsh chemicals, perfumes and solvent exposure. Store separately to prevent contact rub with other jewellery. For deeper cleaning or refinishing, consult an authorised watchmaker or jeweller familiar with gold and gem‑set dials.
Q: Will the 38.5mm size suit my wrist, and what is the bracelet fit? A: 38.5mm is a versatile, balanced size that wears well on many wrists and suits unisex styling. This bracelet fits a wrist up to approximately 20 cm as listed. Share your wrist measurement and we can advise on fit and pre‑dispatch sizing.
Q: Can the bracelet be resized or swapped for a strap? A: Yes—links can be added or removed, and additional links may be sourced (subject to availability). Many Aqua Terra 38.5mm models use a 19mm lug width; we can verify the exact lug size for this reference. If you wish to fit a leather strap, we recommend professional installation to avoid scratching the lugs and to ensure correct end‑link fit.
Q: Is it anti‑magnetic, and how should I handle magnetism? A: While modern Omega movements offer good everyday resilience, this reference is not the full “Master Co‑Axial/Master Chronometer” anti‑magnetic spec. Keep the watch away from strong magnetic fields (speakers, phone cases, induction hobs). If it suddenly runs fast/slow, it may have been magnetised—demagnetising is quick for a watchmaker.
Q: What service interval and care should I expect? A: A routine service every 5–7 years is generally recommended, or sooner if you notice issues such as erratic timekeeping, moisture, or difficult winding. Keep the watch clean with a soft cloth, avoid extreme heat/cold, and have gaskets checked if water resistance is important to you.
Q: What is included, and do you guarantee authenticity and provide warranty? A: This piece comes as a full set with its original box and certificate, as stated. A Retro Tale thoroughly authenticates every item and offers a 12‑month mechanical guarantee, free insured DHL shipping, a 14‑day return policy, and 0% customs fees for EU buyers. We’re happy to share additional photos or confirm movement/reference details on request.
