BALL’s latest bulletproof offering is the Engineer Master II Diver series, a colorful trio of tool dive watches built to BALL’s high standards. Offered for pre-order at a fraction of their MSRP, these bold and purpose-built divers are a limited edition of 1,000 pieces each. There is the Engineer Master II Classic Diver, the Engineer Master II Diver GMT, and the Engineer Master II Diver TMT—all three celebrating BALL’s commitment to undersea exploration and champion free diver Guillaume Néry’s diving accomplishments.As expected, each watch boasts a prolific number of BALL’s trademark tritium gas tubes for deep water visibility (54 on the TMT and 57 on the other two), as well as an internal rotating elapsed-time diver’s bezel. The crown at three o’clock sets the time/date, and the one at two o’clock operates the aforementioned bezel. The Classic measures 44mm and comes in a titanium case, and the GMT and TMT are 42mm and DLC-coated stainless steel. The case back is especially nice, and it features a stamped Mr. Néry rising from the depths.Each of the three models comes in three distinct and colorful combinations. Black with the first quarter of the bezel in white, navy with yellow, and navy with orange. While the navy and yellow/orange bezel combinations look great, I personally really enjoy the simple look of the black and white one.
