Coriental Calendar Antimagnetic World Time watch

For some time I have noticed different watches with the same large watch case. I believe I got really lucky with a specimen bought from Portugal. After gentle cleaning it looks to be in almost mint condition. And the price was only 30 EUR.

The watch measures:
Width: 42 mm
Length: 47,5 mm
Height: 12,9 mm
Lug width: 22 mm

On the nice, shiny steel blue dial it says: Coriental Calendar Antimagnetic. It has an internal non-rotating bezel with cities of the world, thus the seller referred to the watch as a ”World Time”.

In the internal bezel it has a cut-out hole where the month can be read. The month can be set by turning the lower crown. Rather interesting arrangement and it adds a fine splash of red to the design. The months are in Spanish – nice to have a watch that say “mayo” and “julio”.

The back-case could easily be opened using the method with a rubber ball.

On the movement it says: ONE 1 JEWEL UNADJUSTED SWISS PARTS.

Using Ranfft the movement looks almost exactly like a Baumgartner 866. This dates the watch to late 70s or early 80s. In one forum-post it is called the ‘Hong Kong jumbo’ watch, which supposedly were sold up to 1985.

The Coriental watch has probably been assembled in Hong Kong. But why Swiss parts are used for the movement is still unclear to me. Why not make the entire watch in the east?

The watch came without a strap or bracelet. I have put it together with a steel bracelet which gives it a very classical Rolex-like look. But larger at 42 mm and with a fun history.
