This is truly one of my all-time favourite watches. The Omega caliber 321 chronograph is a true classic. The case and dial offer pure balance; with the mechanics being the gold standard in the chronograph world. This watch was fully serviced by a watchmaker who works for Omega and looks essentially like new. The dial and Arrow style hands are completely original and crisp as you see in the photos. There are no major marks or flaws. The caliber 321 famous Omega Moon watch movement is accurate and crisp after a full service. The original steel case measures a full 35.5mm. Don’t hesitate on this one.
