Tissot Waterproof Tank Watch 1930's
This is a special watch and very rare! It's an end 1930's Tissot (Omega) Tank watch with a super nice high grade 'Waterproof' unpolished patented case which measures 23,5x26,5mm (35mm incl lugs). It features a lovely all original black dial with gilt printing and outer grey scale. Movement is Tissot's Cal. 17,5 which has just been serviced. Attached is a nice croco strap. Super desirable and good size tank watch!
