Key Features

Cool and colourful BOSCH diving watch with unusual ‘Octo’ bezel feature, the signature shape of the AP Royal Oak. What’s interesting is that this watch came from the 1970’s when this design was implemented for the first time, so it’s a contemporary, completely original artefact.

The rich blue radiant sunburst patterned dial is decorated with the well known BOSCH brand name, making this timepiece a very nice collectible fashion piece. While the case shape with non-standard convex surfaces really does make the watch quite unique looking.  The sizing is large on the wrist, making it pleasant and comfortable to wear.
