I so want one of these. As part of their 80th Anniversary celebrations, Nikon Japan (don't think those like us outside Japan qualify) will be giving away this clock as a prize to its lucky customers. All you need to do is to be a Nikon user in Japan, own one of the lens in the library of lenses listed and can show proof of purchase and warranty, you can enter the competition.
The clock looks like the very popular Nikon 24-70 f2.8 G Ed lens. Best of all is the sound of the alarm. It is the sound of a shutter firing. How cool is that?
The clock. The hands and markers are luminous.
