Omega Professional Diver 300 M. It has a case diameter of 42 mm and keeps time without any problems. Diver is a 300 meter valuable model. The cord is brand new. (cord buckle after I think) Suitable for wrists up to 25 cm. Blue wavy dial held in the world. Automatic chrono. I added photos of the phosphors very well. As the bezel rotates, it becomes very slightly hard in some places. It never prevents use and rotation. It is a beautiful watch without any problems. High collection value. There are figures up to $4000 on different sites. It will be carefully packaged and shipped in a wooden Omega box. Kind regards.
