Rare KB case manufacturer
1450/808 steel bracelet
This watch is a very example of Omega Speedmaster ST 145.022 from the mid 1980s.
Its case has been made by Bielna SA (hallmark KB), which is not so common among all the case manufacturers used by Omega at that time.
This dial is called Tall & Open S in the MOONWATCH ONLY book, a nickname referring to the height and shape of the capital S of Speedmaster: it is very tall / long and its ends are curly, but much less than the Tall & Closed S variant, produced at the end of the 80s. One can note also the final r of Speedmaster with a low final loop.
The watch is in perfect condition and is fitted with its rare and sought-after original 1450 steel bracelet.
About the model
The Omega Speedmaster, born in 1957, is one of the most iconic wristwatches ever produced. Since 1965, it has been the choice of space programs for over half a century and has been associated with some of mankind’s greatest space adventures, earning it the name The Moonwatch.
Naturally, beyond its professional use for more than sixty years, the Speedmaster, with its incredible history and its timeless design, has appealed to a much wider public throughout the world.
The reference ST 145.022 is the successor of ST 145.012 and the first fitted with the caliber 861.
During the first years of production of the ST 145.022, the year of manufacture was engraved inside the caseback: 68, 69, 71, 74, 76 and the last one 78. After the 145.022-78 (meaning from circa 1982), classification is no longer based on the case reference, but according to the OMEGA code or to visible criteria.
