Q: What is the Omega Seamaster 300M 41mm Watch?
A: It’s an iconic Swiss dive watch in stainless steel with a 41mm case, automatic self‑winding movement, a black wave dial with date, a black unidirectional rotating bezel, and a sapphire crystal. This example is vintage with characterful wear consistent with age.

Q: Is it water‑resistant and can I swim or dive with it?
A: The Seamaster 300M line was originally rated to 300 metres, but water resistance on vintage watches cannot be guaranteed. If you plan to swim or dive, have the seals replaced and the watch pressure‑tested by an authorised watchmaker. Always ensure the crown is fully screwed down and avoid moisture unless recently tested.

Q: Which movement does this model use?
A: It has an automatic Omega movement with a date function. Many 41mm Seamaster 300M models from the vintage era use a calibre based on the ETA 2892‑A2 (e.g., Cal. 1120) and later pieces may use a Co‑Axial Cal. 2500. We can confirm the exact calibre for this watch on request.

Q: How do I set the time and date?
A: Unscrew the crown anti‑clockwise. Position 1: manual wind (about 20–30 turns if stopped). Position 2: quickset the date. Position 3: set the time. Avoid changing the date between roughly 8pm and 2am to protect the mechanism. When finished, push the crown in and screw it down firmly.

Q: How do I use the unidirectional bezel?
A: Align the bezel’s zero marker (triangle) with the minute hand to track elapsed time. The bezel turns anti‑clockwise only for safety in diving. Avoid forcing it clockwise, and keep it clean so it clicks smoothly.

Q: What crystal does it have and how should I care for it?
A: It features a scratch‑resistant sapphire crystal. Clean with a soft microfibre cloth; avoid abrasives, solvents, and ultrasonic cleaners on the watch head to protect seals and finishes.

Q: Does the dial lume glow in the dark?
A: Yes, the Seamaster 300M uses luminous material on hands and markers. The exact lume type varies by production era (earlier tritium vs. later Super‑LumiNova). We can confirm the lume specification for this piece from its dial markings on request.

Q: Will the 41mm size suit my wrist, and can the bracelet be adjusted?
A: 41mm offers a balanced sporty presence suitable for many medium to larger wrists and is commonly worn unisex. The bracelet can be sized; this watch is delivered with 3 extra links. Share your wrist measurement and we’ll size it for you before shipping.

Q: What is included and is it authentic?
A: This watch comes with a pictogram card and 3 extra links (see Accessories). A Retro Tale specialises in authentic luxury vintage accessories; every watch is professionally authenticated and sold with a 12‑month mechanical guarantee.

Q: How often should I service it and what accuracy should I expect?
A: A routine service every 5–10 years is generally recommended, or sooner if you notice timekeeping issues or reduced water resistance. Accuracy varies with age and service history; have it checked if it runs noticeably fast/slow or shows condensation.

Q: Can you verify the exact reference or production year for this watch?
A: Yes. Using the serial number and movement/reference details, we can help confirm the precise reference and approximate production year. Contact us and we’ll provide verification and any additional photos or information you need.
