HANDS Original


DIAM. 36 mm. THICKNESS 13 mm. This INGENIEUR is the first Ingenieur with date that was launched in 1958, while the first versions were non-date. Listed in 1960 at CHF 1'090, it was more than twice the price of the stainless steel version that came in at CHF 460. With a clear punchmark on the lug as well as crisp numbers between the lugs (a characteristic of the early Ingenieurs), a rare example in excellent original condition.
