Notes:  For you consideration is an excellent example of the rare Speedmaster straight writing case-back 145.022. We are surprised this watch has not taken off in value as some of its predecessors considering its rarity and features. This particular example has a beautiful step dial with amazing patina on both the dial and hands. The bezel is in great condition and matches the matte dial nicely. Of course the case-back is what makes this watch so special and this one has nice thick and crisp engravings. This is one of the nicer straight backs you will find out there and we don't expect it to last long.
