It’s not a futuristic wearable laser weapon, but athat can be worn on our wrist. Cool enough? Let’s continue checking 35mm camera introduced in 1957.
Based on Wikipedia, the vintage camera was invented by Australian chemical engineer Dr. Steineck. The 35mm subminiature camera comes with a leather strap that allows photographer to wear it on the wrist. We’re not sure whether it’s the first wearable camera, but it’s curtain that the Tessina is ahead of the times even today.
The wearable camera is able to take 14x21mm pictures. It features a very small twin lens reflex system and has two 25mm f/2.8 Tessinon lenses, one for taking photos, another for viewing via a tiny ground-glass focusing screen on top of the camera. The film advance mechanism consists of a clockwork master spring, a takeup spool and a wristwatch crown-like pullout winder. Each winding allows up to 8 exposures.
