The OMEGA Speedmaster is one of OMEGA’s most iconic timepieces. Having been a part of all six lunar missions, the legendary Speedmaster is an impressive representation of the brand’s adventurous pioneering spirit.

This OMEGA Speedmaster Professional “Moonwatch” features a black dial covered by a hesalite crystal and graced by a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with a central chronograph hand. The black bezel, with its tachymetric scale, is mounted on a 42 mm stainless steel case and presented on a matching bracelet.

At the heart of this chronograph is OMEGA’s mechanical calibre 1861, a descendent of the legendary manual-winding movement worn on the Moon. This timepiece is offered with a special Moonwatch presentation box which contains a "NATO" strap, a strap for astronauts, a tool to change the bracelet and a book highlighting Speedmaster's adventures.

The crown has 2 positions:

1. Normal position (wearing position): when the crown is positioned against the case, the crown ensures that the watch is water-resistant.

Winding: turn the crown forwards until it stops (DO NOT OVERWIND).
Note: do not wind the watch more often than is necessary. For a watch that is

worn all the time, a single winding each day will ensure that it functions correctly.

2. Time setting: hours – minutes – seconds. Pull the crown out to position 2. Turn the crown forwards or backwards. Synchronise the seconds by pushing the crown back to position 1 to coincide with a given time signal.

Note: The calibre does not have a ’stop second’ mechanism. To synchronise, the crown should be gently turned backwards and pressure maintained to stop the seconds hand. Release when the display corresponds to the timing signal and push crown back to position 1.
