In Milan last month Japanese brand plusminuszero launched a watch where the strap slots through the back of the case.

Called ZFW, the design comes with a leather or fabric strap, which can be easily interchanged by sliding it through loops in the case.

Here's some more information from plusminuszero:

The strap of this watch simply threads through the back of the face, and so can easily be changed. Because there are no side pins to secure the watch straps in place, the watch looks like a clean and beautiful single entity. The simple feel of it, like a simple necklace made from a leather cord threaded through a ring, is good.

• High-visible watch face
• Equipped Japanese made quartz movement
• Easily changed strap
