In 1988, the house introduced an automatic version in a more compact case: the Speedmaster Reduced. This reference 3510.50 takes up all its codes, from the black dial to the chronograph pushers.\u003c\/p\u003e\n\u003cp\u003eThe steel case, polished and satin-brushed, measures 39mm in diameter and 12.5mm thick. The black bezel bears the tachymeter scale, which allows an average speed to be read over a distance of one kilometre; the lugs take the bracelet on a Lug width of 18mm, with a Lug-to-lug of 45mm. The Crystal is acrylic, as on the Speedmaster of the period.\u003c\/p\u003e\n\u003cp\u003eThe black dial brings together three sub-dials: sub-seconds, 30-minute counter and 12-hour chronograph counter. Its markers and hands are coated with tritium, the luminous material Omega used before the switch to Super-LumiNova, at the end of the 1990s; over time, the tritium has developed a cream patina, even from one marker to the next and matched to the hands. Dial and hands are original.\u003c\/p\u003e\n\u003cp\u003eThe automatic movement combines an ETA base and a Dubois-Dépraz chronograph module, the architecture that allowed Omega to fit an automatic chronograph into this 39mm case. The watch is fitted on its original steel bracelet, closed by a signed Omega Buckle folding clasp.\u003c\/p\u003e\n\u003ch3 style=\"margin: 40px 0 16px;\"\u003eThree points to note\u003c\/h3\u003e\n\u003cdiv style=\"margin: 20px 0; padding-left: 16px; border-left: 1px solid #e2ddd5;\"\u003e\n\u003cp style=\"margin: 0 0 4px; font-size: 12px; letter-spacing: 0.1em; opacity: 0.45;\"\u003e01\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 18px;\"\u003e\u003cstrong\u003ePatinated tritium\u003c\/strong\u003e — Tritium markers and hands, with patina in the same cream tone.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 4px; font-size: 12px; letter-spacing: 0.1em; opacity: 0.45;\"\u003e02\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 18px;\"\u003e\u003cstrong\u003eAutomatic chronograph\u003c\/strong\u003e — Three sub-dials and a tachymeter bezel, in a 39mm case.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 4px; font-size: 12px; letter-spacing: 0.1em; opacity: 0.45;\"\u003e03\u003c\/p\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cstrong\u003eOriginal bracelet\u003c\/strong\u003e — The Omega steel bracelet and its signed Buckle folding clasp.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3 style=\"margin: 40px 0 16px;\"\u003eWhy choose a vintage Omega watch?\u003c\/h3\u003e\n\u003cp\u003eThis Speedmaster Reduced 3510.50 combines the black three-sub-dial layout of the Speedmaster, evenly patinated tritium and its original steel bracelet, in a 39mm case suited to daily wear.
