Omega Speedmaster Day-Date Automatic Chronograph

Reference 3520.50.00 | Calibre 1151 | Circa 1993–1994

Offered for sale is this attractive Omega Speedmaster Day-Date Automatic Chronograph, reference 3520.50.00, powered by the renowned Omega Calibre 1151 automatic chronograph movement.

Often referred to by collectors as the Speedmaster Triple Calendar, this model combines the iconic Speedmaster design with an exceptionally practical complication set, displaying the day, date, month, chronograph and 24-hour indication.

The black dial features applied baton hour markers, luminous hands, day and month apertures at 12 o’clock, a central pointer date hand and three recessed sub-dials. The result is one of the most distinctive and technically interesting Speedmaster variants produced during the 1990s.

The stainless steel case is fitted with the original tachymetre bezel and presents very well overall. The watch is currently fitted to a quality tan leather strap which complements the vintage character of the watch perfectly.

The caseback has been removed for inspection and photography, confirming the watch retains its correct Omega Calibre 1151 automatic chronograph movement. The movement is signed Omega and appears clean and well presented. The case reference 3520.50.00 has been verified from inside the caseback and the movement serial number 55423158 dates production to approximately 1993–1994.
