214 movement so a Accucell 1 battery is best bet to play it safe it has original lower 1.35v that the watches originally used - ebay and other watch sites sell them altho pricey - if its been rephased for cheaper priced 1.55v modern batteries then a 387s is the typical replacement - altho 394 might work as well - both should be the silver oxide type - looks like a swiss case with the larger M7 stamp and the style of hands - some real expert will chine in eventually
