Hong Kong design studio Raskh has developed the Leverage watch, which features a patented mechanism that reveals a hidden bottle opener concealed in the case body.

Created as Raskh's first watch design, the timepiece uses a specially developed case construction to incorporate the bottle opener without adding excessive bulk to the watch.

"People won't bring a bottle opener with them everywhere, but they will have their daily watch with them every day," the designers told Dezeen.

"Leverage watch can bring a wow moment to the party when everyone sees a person using it to open beer or soda. This is a watch that makes happy hour even happier."

To access the opener, users remove the watch from their wrist before rotating and releasing an octagonal crown located at the eight o'clock position.

With the locking system released, the inner case body slides outwards to reveal a lozenge-shaped indent that can be used to remove a bottle cap.

According to Raskh, the moveable track and hidden opener within the case body is a patented element that "brings a new page of watch community, or you can say a new page of bottle opener".

The watch itself features a classic design, with the bezel and case body combining polished and brushed finishes to create a tactile contrast.

The watch face's indexes are treated with Swiss Super-LumiNova so they glow in the dark. Their enlarged size makes it easier to tell the time while adventuring outdoors at nighttime or drinking at a bar.

A 24-hour sub-dial at the nine o'clock position features luminous paint on the half that is dedicated to nighttime hours. There is also a small date window at the three o'clock position.

Raskh spent two years developing the concept for the Leverage watch and refining the mechanical details to make it as thin and lightweight as possible.

The overall case thickness is 13.8 millimetres and the case size is 44 millimetres, with a dial opening of 33.5 millimetres. The watch features an automatic Miyota 8217 movement and is water resistant to 50 metres.

Raskh is producing the watch in four colourways, three with black dials and one white dial. Nylon and leather straps provided with each watch can be easily swapped out using a quick-release spring bar system.

Recently Bulgari unveiled the world's thinnest watch, which is as skinny as a five-pence coin, while we rounded up six watches designed by Pritzker Architecture Prize-winning architects.
