Built around a round 44.25mm stainless steel case, this Speedmaster Racing carries Omega's Master Chronometer chronograph movement and wears its motorsport heritage naturally. A fixed bezel frames the grey dial, while a transparent case back allows a view of the movement within. Water resistance reaches 50m/167ft, and the crystal is anti-reflective scratch resistant sapphire.
The grey alligator/crocodile leather strap with white stitching secures via a push button deployant buckle at a 21mm lug width, lending a refined contrast to the sport-oriented case. The crown is non-screw-in, keeping the overall profile clean and accessible.
Reference 329.23.44.51.06.001 is offered new and unworn, presenting the Speedmaster Racing as Omega intended straight from production.
