With its sleek satin dial and a perfect 36.0mm Jumbo size case, theres not much more one has to ask from a watch.
Inside housed would be the much revered Cal.751 Day-Date caliber, here the day of the week is set via turning the hands around and the day of the month being set with a special quick-set date function by pulling the crown to a third position.
