145.022 Speedmaster « Bi-color » steel / gold produced for the German market from 1982 to 1988 if I remember well. Mid eighties. Quite a limited run but not numbered. Was originally equipped with a gold bezel with a black Tachymètre insert, unlike the one you refer to. Also the pushers and crown were stainless steel
Now that I am down to one crutch, I can start rotating more watches. ( the crutches took their toll on bracelets and straps) This one for today
