Launched at Basel in 2016, the Omega SeaMaster Professional Deep Black was available in three variations, polished all-black, matt black/red and matt black/blue. The red and blue colours were chosen as these are the first (red) and last (blue) colours visible when diving at depth. The case-back was fitted with a Naiad Lock closure so it always aligned with the case, the 8906 calibre movement was the latest Master Chronometer certified and magnetism resistant to over 15,000 Gauss. The luminous on the dial and hour hand glowed blue, with the minute hand glowing green to allow to accurate reading while diving. The series was discontinued in 2023 when it was replaced by a monochrome version in 39.5mm diameter.
