The 6s37 is a very high-grade, column-wheel chronograph movement with very smooth operation, used in the Fligtmaster Automatic SND001 that retails at around 2000 dollars (and not in the considerably cheaper Flightmaster quartz watches). The Valjoux 7750 is an economy movement, of which the chronograph hour wheel runs without any bearing whatsoever-just in a hole in the base plate. I have been explained multiple times since I was 15 years old that this is a Bad Idea(TM).Terminator 2 wrote:The 6S37A is a Seiko automatic movement as used in the likes of the Seiko Flightmaster.
The Valjoux 7750 is an automatic movement manufactured by a subsiduary of ETA.
I really, truthfully, think that comparing the two would be comparing BMW's to Peugeots.
While I see how it would make business sense to use this movement to supply the demand for "budget auto chronographs", I do think that, from a longevity point of view, it will bite back.
I don't trust this movement, and it seems I am not alone - people more knowledgeable than I have pointed this out too (before I did). Check Timezone - there's an excellent article on this movement somewhere on there.
