Omega designed this variation as the reduced version of the Speedmaster Professional, whose 42mm did not suit every wrist. The design is fully retained: bezel with tachymeter scale, three subdials, pump pushers, downturned lugs.\u003c\/p\u003e\n\u003cp\u003eThe black dial features three subdials arranged according to the model's classic geometry: the sub-seconds at nine o'clock, the thirty-minute counter at three o'clock, and the twelve-hour counter at six o'clock. The hour markers and hands are in \u003cstrong\u003etritium\u003c\/strong\u003e, and they have turned cream. Omega discontinued this material at the end of the 1990s in favor of Superluminova, which remains white indefinitely: a Reduced with a patinated dial therefore belongs to a limited production window.\u003c\/p\u003e\n\u003cp\u003eThe dial is protected by an \u003cstrong\u003eCrystal hesalite crystal\u003c\/strong\u003e, the same material as on the Moonwatch — a domed plexiglass that gives the dial a warmth and edge distortion that sapphire does not reproduce. It is the original version for this reference; only the later variations adopted sapphire.\u003c\/p\u003e\n\u003cp\u003eThe movement is a modular construction: an ETA 2890 automatic base topped by a Dubois-Dépraz 2020 chronograph module. This explains the position of the pushers, slightly offset compared with a hand-wound Speedmaster Professional, and the thickness of the case. The movement of this example has been serviced. The Reduced was produced from 1988 to the early 2010s and today represents the most accessible entry into the Speedmaster collection.\u003c\/p\u003e\n\u003ch3\u003eThree points to note\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePatinated tritium dial\u003c\/strong\u003e — the hour markers and hands have turned cream, a shade that the Superluminova of later generations does not develop.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal hesalite crystal\u003c\/strong\u003e — the same material as the Moonwatch, which scratches but can be polished again, unlike the sapphire on later versions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e39mm format\u003c\/strong\u003e — the Speedmaster in a size that the Professional does not offer, better suited to medium and slender wrists.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy buy a pre-owned Omega?\u003c\/h3\u003e\n\u003cp\u003eAcquiring a \u003cstrong\u003epre-owned Omega watch\u003c\/strong\u003e rather than buying one in a boutique gives access to a Swiss manufacture chronograph at a budget significantly lower than new, in a piece that has already been broken in. The \u003cstrong\u003eSpeedmaster\u003c\/strong\u003e is moreover one of the models whose value is most stable, supported by a history that the maison has maintained since the Apollo missions.\u003c\/p\u003e\n\u003cp\u003eThe Reduced occupies a precise place among \u003cstrong\u003emen's and women's watches\u003c\/strong\u003e: its 39mm format makes it a \u003cstrong\u003esteel chronograph\u003c\/strong\u003e that can be worn equally by both, whereas the 42mm Professional requires a larger wrist.

It loses its luminosity over time and takes on a cream to ivory hue that no one has managed to imitate convincingly. A Speedmaster Reduced with a patinated dial therefore belongs to a limited production window, and immediately stands apart from later examples, whose hour markers remain white.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is hesalite Crystal?\u003c\/strong\u003e \u003cbr\u003eIt is a domed plexiglass crystal, the same material as that of the Speedmaster Professional Moonwatch. It scratches more easily than sapphire, but it can be polished: a polishing paste and a few minutes are enough to remove light marks, which is impossible on sapphire. It also gives the dial a warmth and an edge distortion that sapphire cannot reproduce.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference compared with a Speedmaster Professional?\u003c\/strong\u003e\u003cbr\u003eThree main differences. First, the diameter: 39mm versus 42mm, which changes everything on the wrist. Then the movement: the Reduced is automatic, while the Professional remains hand-wound. Finally, the caseback: pressed on the Reduced, screwed on the Professional. The layout of the subdials, the design of the case, and the Crystal hesalite crystal are, however, shared by both.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHas the case been polished?\u003c\/strong\u003e\u003cbr\u003eMost likely, during the life of the watch. Polishing removes a thin layer of metal to erase scratches; when repeated, it softens the edges and reduces the contrast between brushed and polished surfaces. On this example, the signs are visible on the lugs. This affects neither solidity nor operation, but it matters to a collector attached to the integrity of the original surfaces, and the price reflects this.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this piece suitable for a slim or large wrist?\u003c\/strong\u003e\u003cbr\u003eWith a 39mm diameter, 45mm Lug-to-lug, and 12.5mm thickness, it suits wrists of approximately 16 to 19cm. That is precisely the purpose of the Reduced: to offer the Speedmaster to those for whom the Professional's 42mm is too much. The bracelet measures 18.5cm and remains adjustable by removing links.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e ","brand":"Omega","offers":[{"title":"Default Title","offer_id":53639824343377,"sku":"55629438 3510.50","price":3450.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/8576\/2597\/files\/montre-omega-speedmaster-reduced-3510-50-vintage-39mm-acier-1995-atelier-victor-1.jpg?v=1778613541","url":"https:\/\/ateliervictor.co\/en\/products\/omega-speedmaster-reduced-watch-3510-50-tritium-1996","provider":"Atelier Victor","version":"1.0","type":"link"}
