Oriosa Divers Swiss Chronograph Watch 1960s

Gents 1960s Oriosa divers chronograph.

ORIOSA Divers vintage Swiss manual hand winding chronograph watch 20 ATM.

The hands, stacked indexes and dial are in a very nice condition. The 17 jewel Landeron 248 movement is in superb condition. The watch runs nicely, the chronograph functions are fully working and resets properly. The watch is also keeping accurate time.

There is general light surface marking on the casing. The signed dial is in its original finish, with original hands and chronograph. There is light marking to the dial and the lens has a couple of small marks. Later leather strap has been fitted and the watch comes in a new presentation case.

Measures 38 mm diameter excluding the winding crown, buttons and lugs. The case is chromium plated with a bi-directional rotating bezel and screw on stainless steel back.

Additional notes:
1. The case back states waterproof 20 ATM. With any vintage watch, if should be kept away from water and moisture unless specifically tested.
2. The last photo is taken under bright lighting. This has the effect of removing the gold reflective shimmer from the chromium plating, but is the same watch with a fitted designer leather strap.
3. The chronometer seconds hand is fully straight and any apparent bend in is due to photogralhic distortion through the thick lens.
