Q: What distinguishes this Omega Lady‑Seamaster 28mm (Ref. 220.10.28.60.54.001)?
A: It’s a Seamaster Aqua Terra 150M in a compact 28mm stainless‑steel case, circa 2016, with a shimmer white/cream dial set with 4 diamond hour markers and 8 applied dots in 18K Sedna (rose) gold, matching Sedna‑gold hands, a Seahorse‑embossed closed caseback, and an integrated stainless‑steel bracelet with a deployment clasp.

Q: Is it quartz or automatic?
A: Quartz. This model is powered by OMEGA’s Calibre 4061, a reliable time‑only quartz movement featuring a “Long Life” battery system and an end‑of‑life (EOL) indicator (the seconds hand jumps in four‑second steps when the battery is low). Typical battery life is around 4 years, but this can vary with wear and environment.

Q: Does it have a sapphire crystal?
A: Yes. The watch is fitted with a scratch‑resistant sapphire crystal with anti‑reflective treatment for clear legibility.

Q: Is it water‑resistant?
A: When new, the Aqua Terra 28mm is rated to 150 metres. As this is a pre‑owned piece from circa 2016, we cannot guarantee current water resistance without a fresh pressure test. Please treat it as splash‑resistant only and avoid swimming or showering unless it has been re‑sealed and tested.

Q: Will it fit my wrist and can the bracelet be adjusted?
A: This example is sized to fit a wrist up to 15.5 cm. The bracelet can be adjusted smaller by removing links. Additional links are not included with this listing.

Q: Are the diamonds genuine and how many are there?
A: Yes. The dial features 4 genuine diamond indices set in 18K Sedna gold holders, complemented by 8 Sedna‑gold dot markers for the remaining hours.

Q: What is the condition of this specific watch?
A: Very Good overall. It shows light traces of use, with surface scratches on the case, caseback and bracelet consistent with careful wear. Please review the photos for close‑ups of the hardware.

Q: What is included with the purchase?
A: This listing is “watch only” (no original box or papers). It will be securely packaged and is backed by A Retro Tale’s full authenticity guarantee, a 12‑month movement warranty, and a 14‑day return policy.

Q: How should I care for a quartz Aqua Terra?
A: Avoid prolonged contact with water unless the seals are tested, keep it away from strong chemicals and magnets, and wipe it with a soft dry cloth after wear. Replace the battery every 3–4 years or when the EOL seconds jump appears; have a professional change the battery so gaskets can be checked at the same time.
