This is my favourite of ALL the SINN watches. This 43mm. anodized stainless steel Sinn 156b watch looks very purposeful on the wrist with its neon orange chronograph hands, wide turning bezel and large Arabic vanilla aged luminous numerals. The original winding crown is screw-down. The very famous and fine Lemania 5100 automatic chronograph movement was just meticulously cleaned and is accurate. The dial has aged beautifully. There is some wear in some of the numerals in the date register. The bezel displays amazing condition for the circa 1985 manufacture of this watch. Comes with the original buckle. You are going to love wearing this military piece. You will find yourself staring at this dial often.
