Omega Speedmaster Date | “Reverse Panda” | Tuxedo Dial (Black/White) | 3511.50

The Omega Speedmaster Date Ref. 3511.50 is a distinctive neo-vintage variation of the Speedmaster, combining the collection’s iconic chronograph styling with a practical automatic movement and date complication. Housed in a stainless steel case measuring approximately 39mm, this reference features a black dial with contrasting silver chronograph subdials, fixed stainless steel tachymeter bezel, sapphire crystal, and stainless steel Omega bracelet. Powering the watch is Omega’s Calibre 1155 automatic chronograph movement.

The appeal of the Ref. 3511.50 lies in its classic reverse-panda-inspired dial configuration and compact proportions. The black dial is complemented by three silver-tone chronograph registers, luminous hour markers and hands, and a date window at 3 o’clock, creating a sporty yet balanced appearance. Its 39mm case provides excellent everyday wearability, while the automatic chronograph movement and tachymeter scale retain the motorsport-inspired character that defines the Speedmaster collection.
