Harry Winston Opus 9

Here's a new idea - use loads of diamonds, put them on a conveyor belt, and move the belts to indicate the time. Well maybe the use of diamonds is a novel idea.

This is Harry Winston's Opus 9. You get 2 belts each with 33 baguette cut diamonds, and this is very simple and easy to read.

The 18k white gold case is quite large at 56mm by 48mm wide, and it needs to be 20mm thick to house the mechanism.
