Omega Speedmaster Automatic Ref. 176.0012

It was 1969 when Omega started to produce Speedmasters with different case shapes under the “Mark …” moniker, the first being the MkII. The case shapes were then considered more modern than the Professional case we all know and love and these new variations were sold alongside the Professional.

Several models were made, up to the Mark V. This one is a bit different though. It does not feature a “Mark” designation on the dial. It features the case of the Mark 4 and the movement of the Mark 5. This is why it is commonly referred to as the Mark 4.5, which is a nickname rather than an actual Omega-given title.

Speaking of the movement, it is the Omega variant of the Lemania 5100, the cal. 1045. A more sought-after variant than the caliber 1040, found in the earlier Mark 4. It features not only a central chronograph seconds hand, as you are used to, but also a central minute counter. Positioned directly under the seconds-hand and distinguished through a pair of wings, this frees up space on the dial for a running seconds, hour counter, day-night indicator sub-dials and day-date windows.

As you can spot in the title and on the dial, it is an automatic. So if you are lusting after a Speedy, but feel uneasy about winding your watch every morning, this might just be the watch for you! But there are plenty more reasons to love this quirky Speedmaster.
