Omega 326.32.40.50.06.001 (Pre-owned - Good) — USD 5,078 on eBay

The Speedmaster Racing Co-Axial Chronograph, reference 326.32.40.50.06.001, stands as a testament to Omega's enduring connection with the world of motorsports, a heritage that predates its iconic journey to the moon. Produced between 2013 and 2017, this model revives design elements reminiscent of earlier Speedmaster Racing dials, particularly those from the Mark II series, which featured a distinctive checkered minute track. It represents a modern reinterpretation of the original Speedmaster's sporting DNA, catering to enthusiasts who appreciate both historical provenance and contemporary watchmaking. The aesthetic of the Speedmaster Racing Co-Axial Chronograph is defined by its robust 40 mm stainless steel case, which provides a balanced and versatile presence on the wrist. The grey dial offers a sophisticated backdrop, complemented by the chronograph sub-dials and the characteristic "racing" minute track, which subtly hints at its track-inspired origins. A tachymeter scale on the bezel further underscores its functionality as a precision timing instrument, while the 50m water resistance ensures practical durability for everyday wear. Powering this chronograph is Omega's automatic Caliber 3330, a movement notable for incorporating the brand's revolutionary Co-Axial escapement along with a Si14 silicon balance spring. This advanced horological architecture significantly enhances the watch's long-term precision, stability, and resistance to magnetic fields, thereby extending service intervals and ensuring reliable performance. For collectors, the 326.32.40.50.06.001 is valued for its successful blend of Speedmaster's storied racing heritage with Omega's cutting-edge Co-Axial technology, offering a distinct and technically refined option within the extensive Speedmaster family.
