Its very much like the H3 deck watches that where used and I think its the Mathey Tissot version which was bought by the British Royal Navy its just not been issed and marked up yet. Not had one for years so not sure what they are worth but I think this price leaves a good profit for the next guy, all the best.. Looking at the overall good condition, its a wonderful big watch and unusual in the stand out quality of the movement. Size: approx 62 mm across. Please look at the images as they form an important part of the description, thanks. Any questions please ask.
