Omega Seamaster 16600 9On Beads of rice

Omega Seamaster 166.009 – 23851XXX (1966)

A classic mid-60s Seamaster with all the right details—clean design, warm tones, and fitted on the ever-desirable beads-of-rice bracelet. This is vintage Omega at its most wearable.

The silver sunburst dial has a soft, warm tone that pairs perfectly with the applied indices and clean handset. The date window is subtly integrated, keeping the dial balanced and easy to read. Everything feels cohesive and refined, exactly what you want from this era.

The case has that slightly fuller mid-60s profile, giving it a bit more presence on the wrist while remaining elegant. On the BOR bracelet, the watch feels complete—comfortable, flexible, and unmistakably Omega.

A timeless piece that works just as well daily as it does dressed up.

Technical background

The reference 166.009 is part of Omega’s well-regarded Seamaster lineup from the 1960s, a period where the brand refined its automatic movements and case construction.

Inside is the Omega caliber 562, a reliable automatic movement from the 550 family. Running at 19,800 bph, it is known for its durability and ease of service. This example is a non-quickset variant, meaning the date is adjusted through time-setting rather than a dedicated quickset function.
