This Oriosa Diver Chronograph is dated to the 70s. It has the Landeron 248 movement in it – in superb condition, professionally serviced – cleaned and oiled and ticking good. The case measures 38.2 without the crown and 48.2 lug-to-lug. It is very good condition for its age – all the chronograph functions work perfectly – starts, stops and resets and although there is some wear here and there it looks and feels real good. The dial is champagne coloured one with outer tachymeter scale, the chrono hands are red ones (the center chronograph one and the chrono minutes). The glass is still the original one with some cracks from the ageing, visible under certain angle. The bezel rotates in both ways. Comes on new Nato strap, that suits the watch nicely. It is covered by a limited warranty of 6 months, starting on the date of purchase.
