Dial, case and movement signed, in good conditionDIAM: 35 mm THICKNESS: 13 mmNOTE: During the late 1960's and 1970's Tissot produced many attractive chronographs in the Seastar and Seastar Navigator ranges.This Seastar is equipped with a Lemania cal. 1281, produced at a time when movements and casing parts were being shared between Omega, Tissot and Lemania. Although the movements were all produced by Lemania, they were rebranded for Omega and Tissot watches. The cal. 1281 was developed further to become cal. 1873, a calibre which was used also for the well known Omega Moon watch. The movement was rebranded as the omega Cal. 861 but it is very similar to Lemania 1281.
