Overview
Manual-winding chronograph with historic Moonwatch design and sapphire crystal.
History and context
The Speedmaster was introduced in 1957 and later became closely associated with NASA’s lunar missions. This generation retains the familiar Moonwatch architecture while updating the movement and bracelet.
Design explained
A black step dial, external tachymeter bezel, twisted lugs and three-register chronograph layout create one of the most recognizable chronograph designs.
Movement and technology
The hand-wound calibre 3861 adds co-axial technology and Master Chronometer certification while preserving the ritual of manual winding.
Manufacturing
Swiss-made stainless-steel construction with sapphire crystal in this reference and a bracelet shaped to echo historic Speedmaster designs.
Fit and wearing experience
Although listed at 42 mm, the case shape and compact lug-to-lug help it wear more moderately than the diameter alone suggests.
