Q: What is the Omega Seamaster 300M 36mm Ref 2362.20?
A: It’s a vintage mid‑size diver from Omega featuring a 36mm stainless steel case, an 18K yellow gold unidirectional rotating bezel, a white wave dial with luminous hands and hour markers, a date window at 3 o’clock, and a reliable Swiss quartz movement. It comes on a stainless steel bracelet with a folding clasp and is Swiss made.

Q: What movement does it use and what battery is required?
A: Mid‑size Seamaster 300M quartz models typically use an Omega Swiss quartz calibre (often Calibre 1538). They commonly take a 1.55V silver‑oxide cell such as the 371/SR920SW. Typical battery life is around 2–4 years depending on use. Have a professional watchmaker replace the battery and reseal the case to maintain water resistance.

Q: Will the 36mm size suit my wrist, and can the bracelet be resized?
A: 36mm offers a balanced, mid‑size presence that many consider unisex, suiting small to medium wrists especially well. The bracelet currently fits up to approximately 18cm. We can size it prior to shipping; additional links may be sourced subject to availability and cost—share your wrist measurement for guidance.

Q: Is it water‑resistant and can I swim with it?
A: The Seamaster 300M line was originally rated to 300 metres. However, water resistance on vintage watches is not guaranteed without recent servicing and pressure testing. We recommend avoiding swimming or showering unless the gaskets have been replaced and the watch has been pressure‑tested. Always ensure the crown is fully screwed down before any contact with moisture.

Q: How do I set the time and date on this quartz model?
A: Unscrew the crown anti‑clockwise. Pull to the first click to set the date, and to the second click to set the time (the seconds will stop). Avoid changing the date between approximately 8pm and 2am. When finished, push the crown in and screw it down firmly.

Q: What is the bezel for and how do I use it?
A: The unidirectional rotating bezel is for timing up to 60 minutes (e.g., dives or daily tasks). Align the bezel’s zero marker with the minute hand at the start; elapsed minutes are read against the bezel scale. It turns only anti‑clockwise for safety.

Q: What materials and crystal does this reference have?
A: The watch combines a stainless steel case and bracelet with an 18K yellow gold bezel. It features a white wave dial and luminous markers/hands. The crystal is typically scratch‑resistant sapphire for clear, durable viewing.

Q: What accuracy and maintenance should I expect from the quartz movement?
A: A healthy Omega quartz typically keeps time within about ±15 seconds per month. Replace the battery every 2–4 years and have seals checked periodically if water resistance is important. A full service is only needed if issues arise (e.g., condensation or erratic timekeeping). Keep the watch away from strong magnets and harsh chemicals.

Q: What is included with this watch, and is it authentic?
A: This piece is delivered with no accessories unless otherwise stated in the listing. A Retro Tale specialises in authentic luxury vintage accessories; each watch is professionally inspected and authenticated and includes a 12‑month warranty on the movement.

A: The reference is 2362.20 as listed. Omega serial numbers are typically engraved on the movement and sometimes on the case; production year can be estimated from the serial. We’re happy to share available serial/reference details and additional photos on request.
