This is a gem if we have ever seen one. Look at the silver dial, the the blued steel hands, the movement! This model was sold to the Swedish armed forces just before, during or just after the second world war. Signed “Ed. Heuer & Co. S.A. Switzerland”. and numbered 603768 , this Valjoux 61 is beautifully finished and appears to be untouched by a screwdriver. The case is also signed on the inside back cover and has number 148373. Diameter 50,5mm. Such a mint version of this model must be worth more than the one sold by Hodinkee recently (27th Jan 2021 – $1900).
