Orfina watch with 17 jewels, incabloc, anti-magnetic. Materials: yellow gold-plated case, steel case back. Landeron 248 chronograph movement. Case diameter: 39 mm with crown, 36 mm without crown. Thickness: 12.5 mm. Between lugs: 20 mm. Strap length: 20 cm without the buckle, 21.5 cm with the buckle. Period: 1970s-1980s. This Orfina 17-jewel incabloc anti-magnetic watch is yellow gold-plated with a steel case back. It is in good condition considering when the watch was made. It is in very good working order, except for the chronograph function. When the minute jumps, the second hand stops. If you don't use the chronograph function, it works very well and keeps time perfectly. The buyer is therefore advised to get the watch serviced or adjusted. The reset to zero is slightly offset and also needs adjusting. Dial in good condition, original hands. The Perspex is like new. This chronograph has been cleaned and lightly polished. Lovely item. A new strap has been added, in brown/orange faux leather, with a gold-coloured buckle. Registered and secure shipping by post, with tracking and signature upon receipt. Shipping costs payable by the buyer.
