Orient Avant-Garde Skeleton RE-AV0A01B 42.6mm sapphire crystal anti-reflective 50h power reserve stainless steel bracelet automatic men’s watch The Avant-garde Skeleton, with its modern stylish design is an evolution of the Classic Skeleton.The dial consists of two openwork plates superimposed to show depth with a three-dimensional effect. A honeycomb pattern below and a gear motif on top emphasise the mechanical features of the watch. The Avant-garde Skeleton has refined the exhibition of the mechanical movement unique to ORIENT STAR. Each part of the display can be read easily at a glance, not just the hour and minute hands and indices, but also the power reserve indicator at 12 o’clock and the small second hand at 6 o’clock. Even with the skeletonisation, high legibility is achieved due to the complimentary colour scheme used on the calculated open works on the dial.
