For sale is a very clean steel Omega Constellation 14393 reference from the 1960s. The watch appears to be fully original down to the signed crystal, and the movement is a "special chronometer" movement that had especially high accuracy in testing. See below for more information, and feel free to message me with any questions. Dial: Original, non-luminous white with crosshair dial is in very nice condition. There's just the subtlest patina, and there are a few surface-level specks of flaking clear coat that could probably be removed, but overall, it's an uncommonly nice dial. Case: Original 34.5mm stainless steel 14393 reference case is in very nice, unpolished condition. Bevels on the lugs are still fully visible, and the medallion on the caseback is in very nice condition. Crown: Retains its original signed thin scalloped crown. Crystal: Original (I believe) signed crystal (Omega logo etched in center). Movement: The 561 caliber automatic movement runs, winds, and sets well. The 24.4MM serial dates to 1966 and is a "special chronometer" movement that had especially high accuracy in testing (discussed in this article). This is a pretty late movement for this reference, but it seems to be an all around honest watch so I believe it's just one of the last 14393s. Service history is unknown, so as always with an unserviced watch, a service is recommended prior to regular use. Strap: Comes on the brown DeBeer leather strap pictured. I also have a correct vintage Omega 5-row beads of rice bracelet as well as a period correct red Omega Constellation box (with insert) available at extra cost. Price is $1300 (reduced from $1400) shipped globally. Bank transfer/Wise for payment. OF seller reviews are here. Returns are accepted if the watch is grossly misrepresented. Watch is located in the USA.
