My technician was having a hard time on servicing this Vintage Omega Seamaster Cosmic Automatic Caliber 752 Watch because the movement is an open thru glass. But what I love about an open thru glass movement is that the rotor of the movement is so powerful and the power it provides lasts for long.
The dial has shown some patina due to age. The watch has its original rice bead stainless steel bracelet.
