Speedmaster Professional Moonwatch

“Moonwatch”

Reference 3570.50.00 is the canonical calibre 1861 Hesalite Moonwatch on bracelet, produced from 1996 to 2014. Its 42 mm steel case, black matte dial, closed back, and manual-wind chronograph architecture made it the baseline modern Professional before the 2014 Big Box reference took over.
