Q: What is the Omega Speedmaster 39mm Automatic (ref. 3510.50)? A: Commonly known as the Speedmaster “Reduced”, it’s a vintage, Swiss‑made automatic chronograph with a 39mm stainless‑steel case, black dial with three sub‑dials, and a tachymeter bezel. It offers the iconic Speedmaster look in a smaller, easy‑wear size and dates to around the early 1990s as listed.
Q: Which movement does it use and what is the power reserve? A: Speedmaster Reduced models typically house an automatic chronograph calibre (often Omega 1140/1143, later 3220) based on the ETA 2892‑A2 with a Dubois‑Depraz chronograph module. Power reserve is around 40–45 hours. We can confirm the exact calibre in this specific watch on request.
Q: How does it differ from the Speedmaster Professional “Moonwatch”? A: The Reduced is 39mm and automatic, while the Moonwatch is 42mm and hand‑wound. The Reduced uses a modular chronograph movement (with small seconds typically at 3 o’clock), resulting in slightly different sub‑dial spacing. Both share the classic black dial and tachymeter bezel aesthetic, but the Reduced wears smaller and is generally more convenient for daily use thanks to automatic winding.
Q: Is it water‑resistant and can I swim with it? A: When new, Speedmaster Reduced models were rated around 30 metres. As a vintage piece, water resistance cannot be guaranteed without recent gasket replacement and pressure testing. Treat it as splash‑resistant at best—avoid swimming, showering or submersion, and never operate the pushers under water. Keep the crown fully pushed in at all times.
Q: What type of crystal does it have and how should I care for it? A: Most ref. 3510.50 watches feature a hesalite (acrylic) crystal, valued for its warm look and easy refinishing. Light scratches on hesalite can often be polished with a specialised acrylic polish (e.g., PolyWatch) and a soft microfibre cloth. If you’d like us to confirm the crystal on this exact watch, please contact us.
Q: How do I wind, set the time, and use the chronograph? A: If the watch has stopped, manually wind the crown (about 20–40 turns) to start it, then wear to keep it running. Pull the crown gently to set the time (this reference is typically time‑only without a date). Chronograph operation: top pusher starts/stops; bottom pusher resets to zero. Always stop the chronograph before pressing reset.
Q: Will it fit my wrist, and can the bracelet be resized? A: As listed, it fits wrists up to approximately 18.5 cm. We can size the bracelet prior to dispatch. Additional links may be sourced subject to availability. The Speedmaster Reduced typically uses an 18mm lug width, making strap changes straightforward—share your wrist measurement and style preferences and we’ll advise options.
Q: How do I use the tachymeter bezel? A: The tachymeter scale measures speed over a fixed distance. Start the chronograph at a known marker (e.g., the start of 1 km). Stop it at the end; the seconds hand will point to a number on the bezel that indicates average speed in units per hour (e.g., km/h if you measured 1 km).
Q: What accuracy and service interval should I expect? A: A healthy vintage Omega automatic should keep good everyday time, though performance varies with age and service history (±10–15 seconds/day is typical for many vintage pieces). A routine service every 5–7 years is sensible, or sooner if you notice issues with timekeeping, power reserve, or water resistance. Keep it away from strong magnets and wipe with a soft, dry cloth after wear.
