Vintage 70's Girard Perregaux Railtimer Quartz for Canadian Railways

Circa mid-1970's Girard Perregaux Railtimer Quartz Caliber 352, I believe for the Canadian National Railways. Large heavy gold filled or plated case, approximately 39mm excluding original signed crown. Classic white enamel style railroad dial and hands, some wear to the periphery of the dial. Movement did not fire up when I installed a battery, so it requires attention. An uncommon piece with nice wrist presence. US$275, includes shipping/paypal Canada/US.
