Speedmaster Moonwatch Professional 42 MM - Hesalite

Description:

The Omega Speedmaster Professional Moonwatch (reference 3570.50) is the classic hesalite-crystal chronograph that accompanied NASA's missions and became the first watch worn on the Moon. Crafted from stainless steel, its asymmetrical 42 mm case with twisted lugs offers an iconic, instantly recognisable wrist presence. The black dial, featuring applied baton hour markers, a small seconds sub-dial at 9 o'clock, a 30-minute recorder at 3 o'clock and a 12-hour recorder at 6 o'clock, is powered by the legendary manual-winding calibre 1861 chronograph movement, a direct descendant of the calibre worn on the Moon.

With its fixed black tachymetre bezel, vintage-style hesalite crystal and solid stainless steel case-back, this Speedmaster bridges Omega's spaceflight heritage with timeless tool-watch design. Fitted on a stainless steel mesh bracelet, this watch remains a true icon—equally at home as a daily wear or as a cornerstone of any collection.

This piece presents in excellent condition and was serviced in 2025. It is offered as watch only, with an Omega pouch. No box or papers, and the original bracelet is not included.
