Honouring OMEGA’s legendary role in space exploration, this Speedmaster Moonwatch Professional presents a refined new expression of the iconic chronograph with a striking inverted black and white dial. The 42 mm stainless steel case is paired with a black ceramic bezel featuring a tachymeter scale in white enamel, preserving the unmistakable Moonwatch aesthetic while introducing modern materials and contrast.

Beneath the box-form sapphire crystal, the step dial is constructed using a two-layer design. The polished black main dial is finished with varnish and lacquer for exceptional depth, while the white subdial base brings clarity and visual balance to the chronograph layout. The minute track appears in white on the main dial, while the subdials feature black transferred markings, enhancing legibility and reinforcing the distinctive inverted design.

This Speedmaster is powered by the hand-wound OMEGA Co-Axial Master Chronometer Calibre 3861, visible through the sapphire crystal case back. An advanced evolution of the movement worn on the Moon, it delivers exceptional precision, magnetic resistance and reliability, and is certified to the Master Chronometer standard. The watch is completed with a polished and brushed Moonwatch bracelet featuring OMEGA’s patented comfort release adjustment system.
