SOLD here is this very nice Constellation from the mid 50ies. Excellent condition all over. The case measures 35 mm excluding the crown. Unpolished it is. The two tone dial is excellent too, given its age. Looks stunning IRL. Very even patina. The cal 501 movement is in excellent condition. No mechanical errors in it. The rotor spins reasonably tight. Comes with a period correct and complete box in very good condition. Attached is also a genuinely NOS Omega strap with buckle from the 50ies. I and the watch are located within the EU. My asking is USD 1.600. Registered mail with the Swedish post included. Of course you are welcome to return the watch if it´s not matching my description in text and/ or pictures, and the deviation is material.
