Q: What defines the Omega Seamaster 300M Ref. 2254.50 from 2006?
A: It’s the classic 41mm Seamaster Diver 300M with a stainless steel case and bracelet, black wave-pattern dial, high-visibility sword hands, a unidirectional timing bezel, date at 3 o’clock, and a screw‑down crown with a helium escape valve at 10 o’clock. This example is from 2006.

Q: Which movement does this watch use?
A: The watch is powered by the Omega Calibre 1120, a self‑winding (automatic) chronometer movement with a quickset date, hacking seconds and around 44 hours of power reserve.

Q: Is this reference still in production?
A: No. The 2254.50 is a discontinued generation of the Seamaster 300M, often nicknamed the “Peter Blake” or “sword hands” Seamaster. Its discontinued status makes well‑kept examples particularly sought after.

Q: What type of crystal and bezel does it have?
A: It features a domed, anti‑reflective sapphire crystal and an aluminium bezel insert (not ceramic) with a unidirectional 60‑minute scale for timing dives and everyday tasks.

Q: Is the watch water‑resistant and can I swim with it?
A: This model was originally rated to 300 metres (30 bar). As this is a 2006 piece, we cannot guarantee water resistance without a current pressure test. We recommend treating it as splash‑resistant only and avoiding swimming or showering unless the seals are renewed and the watch is successfully pressure‑tested by a professional.

Q: What is the helium escape valve for and do I need it?
A: The helium escape valve is designed for saturation diving in pressurised environments; it allows helium to safely vent during decompression. For everyday wear—including swimming pools or recreational snorkelling—you won’t need to use it; keep it screwed down at all times.

Q: How do I set the time and date?
A: Unscrew the crown counter‑clockwise. Position 1 (pushed in) is for manual winding. Pull to the first click to quick‑set the date, and to the second click to set the time. Avoid changing the date between about 9 pm and 3 am to protect the mechanism, and always screw the crown back down firmly after setting.

Q: Will this watch fit my wrist?
A: This specific piece is sized to fit a wrist circumference of up to 18.5 cm. The bracelet can be sized down by removing links. Extra links are not included with this listing, but we can advise on sourcing if needed.

Q: What is included with the purchase and is it guaranteed?
A: This listing is “watch only” (no original box or papers). A Retro Tale guarantees 100% authenticity, provides insured shipping, a 14‑day return policy, and includes a 12‑month mechanical warranty on the movement.

Q: What is the condition of this particular watch?
A: Overall Very Good condition with light traces of use. The hardware is shiny with surface scratches consistent with careful wear. Please review the photos for full details.
