Tissot Seastar from 1957: the black original dial has age-related damage of the colour coating in the centre, in particular between 12 and 3 o'clock (visible in particular lighting conditions and with a magnifying glass, please note the images). The "Tissot" logo is superimposed and original, the text "SEASTAR" is printed and also original. The timepiece runs well and is reliable with reduced amplitude. The casing and the dial have (considering the age of the timepiece) only minor to medium signs of wear (a few small dents, but no deep scratches). The satinised, screwed steel base shows minor signs of having been opened. The hands and the superimposed indices have a distinct patina. Calibre: Tissot 27B-21, calibre number 3717508 (from 1957) Watch crystal: synthetic glass, very good condition Steel crown: original Tissot, slightly worn but still easy to grip Diameter (without crown): 34.5 mm x 41 mm Height including crystal: 11 mm The black strap is new, plaited fabric, length: 11.5 + 7.5 = 19 cm All parts of the timepiece (except the strap) are original by Tissot. Early "Seastar" in very good condition. The timepiece is relatively large for the 50s. The authentic, original black dial is remarkable. A Tissot in such good condition that hasn't been tampered with is rare. Insured shipment.
