Q: What is the Omega Speedmaster Reduced Ref. 3510.50? A: It’s a vintage, Swiss‑made automatic chronograph with a 39mm stainless‑steel case, black dial and steel bracelet. Often seen as the compact, everyday counterpart to the Speedmaster Professional, it offers classic Speedmaster styling in a smaller, self‑winding package.
Q: Is the movement automatic and which calibre does it use? A: Yes—this model is self‑winding. Speedmaster Reduced references like the 3510.50 typically use an Omega automatic calibre based on the ETA 2892‑A2 with a Dubois‑Dépraz chronograph module (e.g., cal. 1140/1143/1155). If you’d like us to confirm the exact calibre and service history of this specific watch, please contact us.
Q: How do I wind, set the time, and operate the chronograph safely? A: If the watch has stopped, give it a manual wind (about 20–40 turns of the crown). Pull the crown out gently to set the time, then push it back in firmly. Use the top pusher to start/stop the chronograph and the bottom pusher to reset—only reset after stopping to protect the mechanism. Avoid pressing pushers under water or when the watch is wet.
Q: Is it water‑resistant and can I swim with it? A: The Speedmaster Reduced was originally rated for everyday splash resistance (often around 30m), but water resistance on vintage watches cannot be guaranteed without recent gasket replacement and pressure testing. We recommend avoiding swimming or showering; keep the crown fully pushed in and have seals checked if moisture resistance is important.
Q: Does this reference have a hesalite or sapphire crystal? A: Most 3510.50 examples feature a hesalite (acrylic) crystal, prized for its warm look and ease of polishing. Some variants may have sapphire. We can verify the crystal type on this piece; minor hesalite scuffs can usually be polished with a suitable plastic polish (avoid abrasive cleaners).
Q: How does the Reduced differ from the Speedmaster Professional “Moonwatch”? A: The Reduced is 39mm and automatic with a modular chronograph; the Moonwatch is 42mm and traditionally manual‑wind with an integrated chronograph calibre. Dial proportions, case thickness and crown/pusher layout also differ. The Reduced offers iconic Speedmaster styling in a more compact, self‑winding form but is not the NASA‑certified Moonwatch.
Q: What wrist size will 39mm suit, and can the bracelet be resized? A: 39mm wears well on small to medium wrists and suits many looking for a classic, unisex vintage proportion. The bracelet on this watch is sized to approximately 17.5cm. We can size the bracelet for you, and additional links may be sourced subject to availability. The lug width is typically 18mm, so it also pairs nicely with many leather or fabric straps.
Q: What accuracy should I expect, and how often should it be serviced? A: A well‑maintained vintage automatic chronograph should keep good time for its era, though tolerances vary with age and service history. A routine service every 5–10 years is commonly recommended, or sooner if you notice running fast/slow, reduced power reserve, moisture or stiff pushers. Keep the watch away from strong magnets and have gaskets checked periodically.
Q: What is included with this listing, and do you offer a warranty? A: This piece is delivered with no accessories unless otherwise stated. A Retro Tale guarantees authenticity and provides a 12‑month mechanical warranty on all watches, free insured DHL shipping, a 14‑day return policy, and 0% customs fees for EU buyers. Please see the Accessories section of the item page for specifics.
Q: How do you verify the reference and serial, and can you share more details? A: We professionally inspect and authenticate every watch, verifying the reference (3510.50) and serial. On request, we can share additional photos and help confirm movement, crystal type and bracelet details for your peace of mind.
