This is a large 38.5mm. circa 1948 Vintage Omega housing the very fine and amazingly clean caliber 30T2 which is sparkling, cleaned and accurate. The 30T2 took Omega through WW2 and is known as one of their most robust and fine vintage movements. The case is without any major dings and scratches. The dial is amazing with all natural patina built up over the years. The lume on the hands and dial is original as well. This watch sits slimly on the wrist and measures 9mm. thin. You have to see this watch on your wrist. Such an great looking dial.
