Model: Omega Speedmaster Triple Date/Day-Date "Mk40 Cosmos"
Reference number: 3520.50

Case material: Solid stainless steel with a mix of brushed satin surfaces on the lira lugs and mirror-polished side profiles. The circular case is topped by a fixed steel bezel with a black insert bearing a white tachymeter scale. The crown at 3 o'clock is a knurled, screw-down adjustment crown customized with the "Ω" logo, flanked by two polished cylindrical chronograph pushers, while on the opposite side at 10 o'clock there is a recessed day-adjustment corrector. The case back is sealed by a solid stainless steel screw-down backing engraved at the center with the famous seahorse emblem and the Speedmaster logo.
Dial color: Matte black with high legibility and a smooth finish. The sophisticated technical layout with three sub-dials features on the outer peripheral ring the 31-day month scale printed in white, accompanied by a white minute track and luminous baton hour markers. It presents main hour and minute baton hands in white and luminous, along with a central slim seconds chronograph hand with a luminous tip and a fourth central hand dedicated to the date with a white tip. At 3 o'clock the applied logo and the signature "Ω OMEGA/Speedmaster/AUTOMATIC" stand out.
