Omega 3529.50.00 (Pre-owned - Excellent) — USD 5,320 on eBay

The Omega Speedmaster Automatic Date reference 3529.50.00 occupies a significant niche within the esteemed Speedmaster collection, distinguishing itself from the manually wound "Moonwatch" Professional models. As part of the Speedmaster Date series, it offered collectors an automatic winding chronograph experience complemented by a practical date display, a key differentiation from its space-faring counterparts. Produced between approximately 2000 and 2005, this reference represents an era when Omega expanded the Speedmaster's versatility to cater to a broader audience seeking daily wearability with chronograph functionality. Adorning the wrist, the 3529.50.00 presents a balanced and classic aesthetic. Its stainless steel case measures 39 mm in diameter, offering a more compact and understated profile compared to the traditional 42mm Professional. This size, shared with other automatic Speedmaster variants often colloquially referred to as "Reduced," contributes to its ergonomic appeal. The watch is completed with a stark black dial, providing excellent contrast for its chronograph subdials and ensuring legibility for both timekeeping and elapsed measurements. Powering the reference 3529.50.00 is the automatic Omega Caliber 1152. This self-winding chronograph movement, based on the robust ETA 7750 architecture, was a workhorse for Omega during this period, known for its reliability and ease of service. The inclusion of the date complication at the 3 o'clock position enhances its utility as an everyday timepiece, while the 30-meter water resistance rating reinforces its design as a sophisticated yet practical instrument for urban environments rather than extreme conditions. For collectors, the 3529.50.00 holds appeal as an accessible entry point into the iconic Speedmaster lineage. Its automatic movement and more compact dimensions offer an alternative for those who appreciate the Speedmaster design language but prefer the convenience of self-winding and a smaller case size. The Speedmaster Date models, like this reference, highlight Omega's strategy to diversify the collection beyond its lunar legacy, providing a compelling blend of heritage-inspired design and modern functionality.
