This watch is unique... I've never seen a similar Omega Tissot before! It's from the 1930's and has a stunning, simple but elegant Art-Deco dial in all original condition. It features mirror accents and has both Omega Watch Co and Tissot printed. This was done right after Omega bought Tissot in order to improve the Tissot brand name... mainly in South-America. It's one of the largest tank watches, measuring 25,5 x 42,8mm. It's fully signed, even the Cal 20 movement has both brand names on it. Icing on the cake is a super rare and beautiful original bachelite box. Attached is a pigskin period style strap. Wonderfull, elegant and an important Omega Tissot.
