I am selling this item because I purchased it on this site but no longer use it. This is the "SEAMASTER COSMIC," a model said to be designed to evolve the standard Seamaster into a more sporty watch, with the pet name "COSMIC" representing space. It features a distinctive one-piece case known as "Unicoc." The time is adjusted by pulling the crown out one step, and the date advances by pulling it out two steps. First come, first served. Please consider that this is an old item and may require an overhaul. The item is a used or stored item, so please refrain from purchasing if you are sensitive to such things. Returns or cancellations are not accepted after purchase. Please check the condition in the photos and purchase with your understanding. Immediate purchase is welcome.
