Hey thanks
I am, to be honest, skeptical of A7750's modified or not although I know some people on this group advocate getting them serviced. I am not sure if this view is based on actual experience or by word of mouth. Have you had this done on your watches before?
Its a shame about the spacing on a quartz - you can, in fact, get some with a sweeping second hand!!
Another alternatative perhaps could be to perhaps obtain a straight mechanical hours/minutes/seconds/date movement and therefore disable the chrono dials, the functionality of which is probably of secondary use on ths type of watch.
All a matter of taste, I guess
