The heart of this chronograph, Omega’s celebrated Caliber 321, is a movement of historical significance that underscores the watch’s value to enthusiasts. Known for powering Omega’s chronographs from the 1940s through the 1960s, including NASA-certified watches for the Apollo moon missions, Caliber 321 is prized for its column-wheel mechanism, lauded for both its smooth action and reliable precision. This movement’s legacy has made it one of the most revered vintage chronograph calibers, especially as Omega suspended its production in 1968, adding rarity to any model housing it. The 35mm case, compact by today’s standards, epitomizes the design preferences of the era and frames the dial with subtle, finely crafted lugs that keep the watch balanced on the wrist.

The Seamaster reference 2451 with Caliber 321 and a salmon dial not only embodies a pivotal moment in Omega’s chronograph history but also offers a charming, vintage elegance that complements modern style. It’s a watch that speaks to Omega’s relentless pursuit of precision while also satisfying the collector’s quest for unique timepieces with storied movements and refined aesthetics.
