Nepro “L'Intégrale”

European Watch Clock and Jewellery Fair 1989 BF 338
By eliminating the protuberance created by the traditional watch crown, time-setting systems directly by the watch crystal make inventive new designs possible. Called “L’Intégrale”, this model is entirely sheathed in fine leather. This new electronic setting system turns pressure on the crystal into impulses that advance the hands. (NEPRO “L’Intégrale”)
