Omega Speedmaster Professional Moonwatch | Manual Wind | Ref 3570.50 I

The Omega Speedmaster Professional Ref. 3570.50 is one of the most iconic watches ever made—this is the true modern Moonwatch, carrying the same design language worn during NASA’s historic lunar missions. With its 42mm stainless steel case, black dial, and hesalite crystal, this reference stays incredibly faithful to the original Speedmasters that went to the Moon.

The dial is as clean and purposeful as it gets. A matte black background, crisp white printing, and the classic tri-compax layout create perfect legibility. The tachymeter bezel and “dot over 90” detail reinforce its racing roots, while the overall design remains one of the most recognizable in horology.

The hesalite crystal is another key detail—it’s not just nostalgic, it’s part of what makes this watch a true Moonwatch. Unlike sapphire, it gives the dial a warmer, slightly distorted vintage look that collectors love.

Condition

Please review the photos carefully for an accurate representation. Light scratches or signs of wear consistent with age and normal use may be present and do not affect the functionality of the watch. Hesalite crystals may show light surface marks but can be easily polished.
