Omega Speedmaster 38 38mm steel on steel

This Speedmaster 38 mm is characterised by a number of distinctive elements, making it a fine celebration of the critical eye care provided by Orbis International and its Flying Eye Hospital.
The watch features a stainless steel case and bezel with a tachymeter scale on a blue aluminium ring.
The sun-brushed blue dial includes horizontal, light-blue oval subdials and a vertical oval date window at 6 o’clock. The indexes are rhodium-plated while the hands are also rhodium-plated or blue. The blue central seconds hand includes a special Orbis Teddy Bear counter-watch_case_weight.
The watch has a stainless steel bracelet, an Orbis Teddy Bear stamped on the caseback, and is driven by the OMEGA Co-Axial Calibre 3330.
