BALL – Engineer Master II Skindiver Heritage DM3308A-SC-BK

The Ball Engineer Master II Skindiver Heritage is an extension of the sea exploring line which was launched in partnership with multiple world champion constant weight freediver Guillaume Nery. A certified chronometer, it has been tested by the Official Swiss Chronometer Testing Institute (COSC) for its accuracy. To gain COSC certification, it must be accurate to -4/+6 seconds per day.

With a 42mm stainless steel case, the Skindiver Heritage has a black uni-directional rotating bezel with a luminous ceramic top. Similarly, the dial is also black. To ensure night visibility, 31 micro gas tubes on the hands and dial glow brightly in the dark. Also, an anti-reflective sapphire crystal protects the dial. Additionally, the heavy-duty crown screws-in to the case. Water resistant to 30 bars (300m)/990ft, the Skindiver Heritage is also anti-magnetic and shock resistant. Finally, the robust stainless steel bracelet is fitted with a folding buckle.
