Purchased from a well-known vintage watch store. I've decided to sell this watch because the watch I really wanted has become available. This particular piece is in unbelievably good condition. Furthermore, it comes with the original bracelet and is a full original parts model. It has also just been overhauled. Here's the description: ・ref: 535.007 ・cal: 638 ・Manual winding ・Year: 1967 ・Size: 31mm ・Bracelet: Long enough for men with thick wrists. My ideal bracelet length is 17.2cm, but this watch has a buckle with two extra holes for further adjustment. This length is quite rare. ・Condition: Very good condition with no major scratches. ・Description: Features a bidirectional black bezel and a matte black dial typical of diver's watches. The case is a dustproof and waterproof screw-back case. The distinctive sloping shoulder case shape, similar to the C-line case designed by Gerald Genta, is a striking feature among diver's watches and is a design characteristic of Omega. The manual winding caliber 630 is also in good condition, making this a watch you can use for a long time. The original metal bracelet is also included, making this a watch you can enjoy for years to come. ・Accessories: Warranty card and box from the store where it was purchased.
