Speedy Mark IV Questions... Posted By: JohnK Date: 5/9/07 15:02 GMT

So...I have just had a Speedy Mark IV arrive and I a couple of questions...

Why does it say 1040 instead of 1041

Why do you think that the movement should say 1041? They never shipped that way...

OMark Series Article: Omega Speedmaster Professional Mark IV (1973):

Please note the first sentence of the third paragraph after the picture caption.

Dimensions of Selected Omega Chronographs:

Please note the Calibre column on line 3 of the Mark Series chart.

Marco Richon's History of the Omega Speedmaster Tables:

Please note that while both the Mark IV and the Speedmaster 125 were introduced in 1973, onlt the 125 sported the c.1041 movement. In fact, the Speedmaster 125 was the only model to use the c.1041 movement.

and why the does the movement number begin with an "R" instead of the usual Omega format? Replacement Movement?

And a couple of pics of the movement:

Yeow! I have a 23" Apple Cinema Display and it screams "No Mas!" to a 2800+ pixel scan. Seriously, anthing more than about 1000 pixels wide is overkill on forums. Try to crop anything larger.
That's better.
It looks ok to my eyes. I don't have an explanation for the "R" serial number, but I don't see anything untoward.
Hope this helps.
