The Omega Speedmaster, a name synonymous with lunar exploration and horological excellence, boasts a rich and diverse history. While the hand-wound chronograph movements of the legendary Moonwatch hold a special place in the hearts of collectors, Omega also incorporated the robust and versatile Valjoux 7750 movement into several Speedmaster models. This article delves into the fascinating relationship between the Omega Speedmaster Automatic Date and the modified Valjoux 7750, exploring its features, history, and place within the broader context of Omega's chronograph legacy. We'll also examine the Valjoux 7750 itself, exploring its specifications, reputation, and current market value.
The Omega Speedmaster Automatic Date (Ref. 3511.50) and its Modified Valjoux 7750 Heart
The Omega Speedmaster Automatic Date, specifically reference 3511.50, stands as a prime example of Omega's utilization of the Valjoux 7750. This model, often seen in pre-owned markets and appreciated by collectors like @watchwatches2020 (whose photo provides a visual testament to its enduring appeal), showcases a modified version of the ETA 7750 – a movement originally designed by Valjoux before its acquisition by ETA. This modification is crucial to understanding the watch's position within the Omega Speedmaster lineage. Unlike the manually wound movements of the iconic Moonwatch, the 3511.50 offers the convenience of automatic winding, thanks to the 7750's robust automatic mechanism. This modification, however, extends beyond simply adding an automatic winding system. Omega tailored the 7750 to fit its design specifications and brand identity, resulting in a chronograph that maintains a level of refinement and quality expected from Omega.
Valjoux 7750: A Chronograph Workhorse
The Valjoux 7750 itself is a legendary movement in the world of horology. Its widespread adoption by numerous watch brands is a testament to its reliability, versatility, and relatively affordable production cost. This automatic chronograph movement boasts a substantial 48-hour power reserve, a feature highly desirable for daily wear. Its architecture is a marvel of engineering, combining an automatic winding system with a column-wheel chronograph mechanism, a feature often associated with higher-end movements. The column-wheel contributes to the precise and crisp operation of the chronograph functions, further enhancing the watch's functionality and appeal.
Valjoux 7750 Best Price:
Finding the best price for a Valjoux 7750-powered watch, especially a pre-owned Omega Speedmaster, requires careful research. Online marketplaces, auction sites, and reputable pre-owned watch dealers offer varying prices depending on the watch's condition, box and papers, and market demand. Condition is paramount; a watch in excellent condition with original accessories will command a higher price than one showing significant wear. Careful comparison shopping and understanding the current market trends are essential to securing a good deal. Remember to factor in potential service costs, as older movements may require servicing to maintain optimal performance.
