Bulova Automatic 115334-W "Big Block" vintage men's watch, runs

This classic Bulova watch from the 1970s has a Bulova cal. 11AOACD 17 jewel automatic movement. The movement looks pristine. The dial is also in amazing shape. The all silver case and Bulova-branded bracelet contrast with a blue and silver dial. The hexagonal shaped case is so unique and very 1970s. The watch is running but I do not have the ability to test for accuracy. It likely needs a service.  Condition: This watch is in great shape for it's age. The case and bracelet have scuffing. The crystal does have some scratching, which is shown best in the video. There is a spot of discoloration on the caseback. Runs but I do not know it's accuracy. Please see photos for full condition.  Measurements: Case size: 41mm x 37mm Thickness: 10mm Band width: 22mm (tapers) Wrist size: 7 (can be adjusted some)
