Q: What is the Omega Seamaster 300M 36mm Ref. 2622.50? A: It’s a late‑1990s mid‑size version of Omega’s professional dive watch, featuring a 36mm stainless‑steel case and bracelet, black wave dial with luminous markers, a unidirectional 60‑minute bezel, and a screw‑down crown. This listing is vintage, in good condition, and delivered with its box as stated.
Q: Which movement does this model use? A: The 1990s Seamaster 300M mid‑size family was offered in both automatic (often Omega Calibre 1120, ~44‑hour power reserve) and quartz (often Calibre 1538) versions. Exact calibre can vary by reference; contact us and we’ll confirm the movement in this specific watch.
Q: Is it water‑resistant and suitable for swimming or diving? A: When new, Seamaster 300M models were rated to 300 metres. With vintage pieces, water resistance cannot be guaranteed without recent gasket replacement and professional pressure testing. Avoid swimming or showering unless the watch has been freshly tested, and always ensure the crown (and helium valve) are fully screwed down before any moisture exposure.
Q: How do I set the time and date safely? A: Unscrew the crown anti‑clockwise. For automatic: Position 1 winds the movement (20–40 turns if stopped), Position 2 quicksets the date, Position 3 sets the time. For quartz: Position 1 quicksets the date, Position 2 sets the time (no winding needed). Avoid changing the date between roughly 8pm and 2am. Push the crown in and screw it down firmly when finished.
Q: Does it have a sapphire crystal and what type of lume is used? A: Most Seamaster 300M models from this era feature a scratch‑resistant sapphire crystal. Lume on late‑1990s examples is typically Super‑LumiNova (earlier dials may have tritium). We can verify the crystal and lume on this exact watch upon request.
Q: What is the bezel made of, and how should I use it? A: The unidirectional bezel typically has an aluminium insert. To time a dive or interval, align the zero marker (lume pip) with the minute hand; the elapsed minutes are then read off the bezel. Aluminium inserts can show wear or fade over decades—avoid impacts, chemicals and abrasive cleaning.
Q: What is the helium escape valve and do I need it? A: The valve at 10 o’clock releases helium during professional saturation‑diving decompression. It’s not needed for everyday use—keep it fully screwed down to help maintain water resistance. Only trained divers should operate it during saturation decompression scenarios.
Q: Will it fit my wrist, and can the bracelet be resized? A: This watch fits wrists up to approximately 19cm as listed. The stainless‑steel bracelet can be sized by adding/removing links, and many 300M bracelets include a diver’s extension in the clasp. The mid‑size 36mm version typically uses 18mm lugs, so swapping to OEM rubber or NATO straps is straightforward with the correct width.
Q: How does the 36mm wear compared with the 41mm Seamaster 300M? A: The 36mm mid‑size offers a balanced, vintage‑proportion profile that suits small to medium wrists and wears well unisex. Compared to the 41mm, it’s lighter and more discreet, yet retains the core Seamaster design cues and professional functionality.
Q: What servicing and accuracy should I expect? A: For automatic versions, a routine service every ~5–10 years is sensible; accuracy depends on age and service history. For quartz, typical battery life is ~2–3 years. Keep the watch away from strong magnets, have gaskets inspected if water resistance is important, and wipe with a soft microfibre cloth after wear.

All watches include a 12‑month movement guarantee, free fully insured DHL shipping, a 14‑day return policy, and 0% customs fees for EU buyers.
