To commemorate that milestone in the company's history, BALL launched the Skindiver Heritage series in the form of three distinct groups that are differentiated by the movement used. The most affordable group features BALL's RR1102 automatic caliber with a day-date complication (built on an ETA 2836-2 base); the middle group uses the BALL's RR1102-C caliber with COSC-certification; and the most expensive group used the BALL in-house RRM7309-C movement with 80-hour power reserve and COSC-certification but drops the day for a date-only complication.
After looking at the three options, I ended up with the most affordable option available, the model featuring the base movement RR1102 without COSC certification and paired with a rubber strap. The DM3208B-P1-BE was the model I chose.
