The Omega Speedmaster reference 175.00.43 is part of the reduced automatic Speedmaster range introduced in the late 1980s, offering a more compact and accessible interpretation of Omega’s most famous chronograph. While the core design draws directly from the Speedmaster Professional’s layout — with its tri-compax register arrangement, tachymeter bezel, and hesalite or sapphire crystal options — this version distinguishes itself through its blue dial, a notable departure from the model’s traditional black. The case, measuring approximately 39 mm, preserves the lyre-lug silhouette and fixed tachymeter bezel familiar to the Moonwatch lineage, yet its proportions and automatic winding reflect a shift in Omega’s 1990s catalogue toward daily-wear versatility.
Technically, the 175.00.43 houses the Omega calibre 1140, a modular chronograph movement built on the robust ETA 2890-2 base with a Dubois Dépraz chronograph module. This arrangement allowed for reduced case thickness compared to an integrated chronograph design, as well as the convenience of automatic winding — a departure from the hand-wound calibre 321 and 861 used in the Speedmaster Professional. While purists sometimes debate the merits of the modular approach, these movements were known for reliability, ease of servicing, and accuracy in everyday use. The blue dial variant also features luminous hour markers and hands, ensuring legibility in varied lighting, while its colour palette gave the watch a distinct presence among the otherwise monochrome Speedmaster offerings of the period.
From a cultural and collector standpoint, the reference 175.00.43 occupies an interesting space in Speedmaster history. It embodies Omega’s strategy in the late 20th century to broaden the Speedmaster’s appeal beyond its NASA and Moonwatch associations, introducing variations that could attract both seasoned collectors and new buyers. The blue dial versions, produced in smaller numbers than their black-dial counterparts, are less frequently seen on the market, adding an element of scarcity. For enthusiasts, this model reflects a transitional era for Omega — when the brand balanced heritage design cues with contemporary materials, colour experimentation, and practical automatic calibres — marking it as a distinctive entry in the wider Speedmaster family tree.
