Good day. I sell watches of the world famous brand Omega. Worn very little, a state close to new. For a long time lay, hence the marks on the packaging box. Material - 18k gold / stainless steel. Waterproof up to 30 m, glass - sapphire. Model 1448/431. On the lock number 11 (the diameter of the bracelet in a buttoned form is about 65-68 mm). Installed a new original battery. The course is magnificent, as befits a chronometer of this class.
