Build-your-own smartwatch raises $1.5m

A customisable smartwatch with removable sensors has smashed through its crowdfunding target.

The Blocks project had hoped to raise $250,000 (£164,000) but backers pledged six times that amount.

The creators say the modular design, which lets wearers choose which sensors they want on their wrist, makes the device future-proof and upgradeable.

Co-founders Serge Didenko and Ali Tahmaseb showed a prototype to BBC technology reporter Chris Foxx.
