Hi, Up for sale my Nivada Grenchen Aviator Sea Diver Chronomaster. It is the second execution circa 1970 powered by a Valjoux 23 in perfect condition. The particularity is the red lollipop sweep second hand and a slight tropicalization of the dial. The tritium lume is perfect and untouched, please note on the sweep second hand a small lack of lume. Asking price is 2000€ shipped from France (Paris). PayPal please add 4%. Thanks to OF for the space, T.
