On the wrist since Dec. 16, my 35-year old Rolex Date-Just, one owner (me) with the calibre 3135 movement in it. My all time favourite Roman numbered dial with applied markers. 35 seconds fast in 19 days, so within one minute per month. Still wearing my Seamaster bumper automatic, date at 6 with calibre 355 movement, pristine hobnail dial, about 70 years old, and functioning flawlessly.
