The 145.012 is the last Speedmaster powered by thelegendary column-wheel Caliber 321 movement, and also the last Speedmaster flown by NASA during the Apollo missions, including being strapped to the wrist of Michael Collins during Apollo 11. This important moment in history has solidified the Speedmaster as one of the most important watches ever made and one of the most sought-after vintage watches in the world.

This 145.012-67 retains all of its original key components save the crown, with its signature stepped dial with wide-spaced "T"s, original hands, DON bezel, and pushers. The case shows wear typical with age but appears unpolished with sharp edges all around. The movement, a 25.00 million serial number, was just serviced and is in excellent working order.

Take a look at the photos and our condition description below:

Case: 42mm stainless steel case in excellent condition. The case appears unpolished, the edges on the top of the lugs are very crisp as are the underside of the lugs and the transition from the brushed to polished area on the case sides. The case side brushing while not as crisp as new from years of wear still has the graining texture from the original brushed surface. Pushers are original with typical disocloration on the tubes as shown. Crown is a service replacement, the threaded post of the original flat foot crown was damaged beyond repair and had to be replaced during service.

Bezel: Original dot over 90 (DON) bezel in very good condition with numerous small spots of edge wear as pictured.

Dial/Hands: Dial is original stepped tritium with applied logo and wide spaced "T"s in excellent condition. Lume is original tritium and intact with a very attractive creamy even patina. Hands are also original, the chronograph seconds hand has a correct wide head, the stalk of the hand shows minor discoloration and it appears the original lume has been stabilised in the past as color is a b it darker and the glow from the tritium is a bit fainter under a UV flashlight. Hour and minute hands have a slightly darker patina than the hour markers.

Caseback: Original 145.012-67 caseback in very good condition as pictured. Hippcampus is complete, minor parts of the Speedmaster text show some fading but all engravings are present.
