I have recently discovered a vintage Tissot timepiece situated in storage beneath my grandfather's bed, and I am seeking a technical evaluation of its significance. As I am currently processing information regarding the brand's historical catalog, I would appreciate it if the community could identify this specific reference and determine its current market valuation. The objective is to ascertain whether the cost of a professional mechanical restoration is justified by its potential appraisal value or if it should remain classified as a sentimental heirloom.
