Q: What is the Omega Seamaster 300M 41mm Automatic (1999) Ref. 2531.80.00? A: It’s a classic “Professional” Seamaster with a 41mm stainless steel case, blue wave dial, blue unidirectional bezel and a stainless steel bracelet with folding clasp. This era typically houses the automatic Omega Calibre 1120 with date, a screw‑down crown and the signature helium escape valve at 10 o’clock—an iconic, versatile dive watch from Switzerland.
Q: Is it water‑resistant and can I swim with it? A: The model was originally rated to 300 metres, but water resistance on vintage watches cannot be guaranteed without recent servicing and pressure testing. We recommend avoiding swimming or showering unless the gaskets have been replaced and the watch has been professionally tested. Always keep the crown and helium valve fully closed before any exposure to moisture.
Q: Which movement does it use and what accuracy/power reserve should I expect? A: This reference typically features the automatic Omega Calibre 1120 (based on ETA 2892‑A2), with an approximate 44‑hour power reserve. When healthy and properly serviced, accuracy can be within chronometer tolerances (around −4/+6 seconds per day), though performance varies with age and service history. We can confirm the exact calibre in this piece on request.
Q: How do I set the time and date safely? A: Unscrew the crown anti‑clockwise. Position 1: wind the watch (about 20–30 turns if it has stopped). Position 2: quickset the date. Position 3: set the time. Avoid changing the date between roughly 8pm and 2am. When finished, push the crown in and screw it down firmly to help maintain water resistance.
Q: What is the helium escape valve for, and should I use it? A: The manual helium escape valve (at 10 o’clock) is designed for saturation diving to release built‑up helium during decompression. For everyday wear—including swimming—you do not need to use it. Keep it closed at all times unless you’re in a professional saturation diving environment.
Q: What materials are used for the crystal and bezel? A: The Seamaster 300M of this era typically features a scratch‑resistant sapphire crystal and a blue aluminium bezel insert on a unidirectional rotating bezel. The dial’s luminous markers and hands provide legibility in low light. We can verify the crystal type on this exact watch upon request.
Q: Will it fit my wrist, and can the bracelet be resized? A: This watch fits a wrist up to approximately 18 cm (as currently configured). The stainless steel bracelet can be sized by adding/removing links; additional links may be sourced subject to availability. Share your wrist measurement and we’ll size it for you prior to dispatch.
Q: What is the lug width and can I use other straps? A: The 41mm Seamaster 300M typically has a 20mm lug width, making it compatible with many OEM and high‑quality third‑party straps (rubber, NATO, leather). Use correctly sized spring bars and ensure any strap or end links are designed for the 300M case for proper fit and security.
Q: What servicing and care should I plan for? A: A routine service every 5–10 years is common, or sooner if you notice issues (e.g., running fast/slow, moisture, power reserve drops). Have gaskets inspected/replaced if water resistance is important. Keep it away from strong magnets, rinse with fresh water after any salt exposure, and wipe with a soft microfibre cloth after wear.
