How Strategic Sourcing Built Google’s Repairable Smartwatch

The global shift toward sustainable product design has placed repairability at the centre of innovation across consumer electronics. As pressure mounts on manufacturers to reduce electronic waste, smartwatches present a unique challenge due to their space-constrained nature.

Google's Pixel Watch 4 programme demonstrates that advanced repairability and compact form factors need not be mutually exclusive. It offers a blueprint for how the industry might balance user experience with environmental responsibility.

Repairable design underpins the programme, with the goal of keeping devices useful for longer. The team treated repair as an integral part of the product experience. After early praise for the first-generation watch was tempered by critiques, Google set a clear "North Star" for serviceability.

Cross-functional teams involving industrial design, engineering, operations, sourcing and sustainability collaborated to map shortcomings. They prototyped alternatives to define a shared vision. This guided decisions to extend product life without trading away protection, performance or aesthetics.

This approach reduces waste from premature replacement and supports better ownership experiences. With Pixel Watch 4, the challenge was delivering that outcome without compromising the device's sleek profile.

“Creating a repairable smartwatch isn’t easy,” writes Kate Brandt, Chief Sustainability Officer at Google, on LinkedIn.

“It required seamless collaboration across industrial design, engineering, operations, sourcing and sustainability teams.

“This partnership is what allowed us to move from ‘disposable’ tech to a design that truly stands the test of time.”

Sourcing sustainable component alternatives

Adhesive is common in thin devices but slows repairs and can be unreliable when reapplied. Pixel Watch 4 replaces adhesive at key service interfaces with a dual-gasket system. This maintains 5 ATM and IP68 protection both before and after a repair.

Because gaskets typically add height, the internal electromechanical stack was aggressively miniaturised to preserve the profile. Electronics were rebuilt around a compact, densely populated PCB that uses hot bar connectors to cut thickness.

Haptics moved to a custom linear resonant actuator. This component is 10% smaller by volume while delivering 15% more strength at the same power. These sourcing moves enable longer product lifecycles through faster, cleaner and more consistent repairs.

Optimising battery energy density

Power and charging changes further align space efficiency with serviceability. A custom-shaped stacked-cell battery increases volumetric energy density by 50% compared with the previous roll-stack approach. This raises capacity without adding thickness.

The new layout enables direct battery access without disconnecting the biosensor hub, simplifying a frequent repair step. Charging contacts shifted from the bottom of the case to the side, paired with stronger magnets for a more intuitive connection.

This delivers 25% faster charging than Pixel Watch 3. Together with a new curved display, these decisions reduce overall volume by 4%. The watch feels slimmer on the wrist and is more straightforward to disassemble.

These engineering and sourcing choices illustrate how component selection directly impacts the serviceability of the final product.

All sustainability, net zero and sustainable supply chain leaders should attend:

Co-located with Procurement & Supply Chain LIVE, these events brings together CSOs, ESG leaders and senior decision-makers at a moment when sustainability, supply chains and commercial performance are increasingly interconnected.

Tickets can be booked online today for The Net Zero Summit and The US Summit. Group discounts available.

Supply chains for repair

Removing adhesive required a new retention system to ensure reliable gasket compression. Traditional screws were unsuitable for the bottom module due to size, radio performance and aesthetic constraints.

The team developed a concealed sliding-wedge mechanism within the band attachment ports. This established two critical retention points. Achieving a uniform radial seal with just two points demanded tight control of manufacturing variation.

Extensive tolerance analysis ensured consistent compression, durability and water resistance. Building an accessible repair ecosystem is equally important, as sustainability depends on accessible know-how and parts.

Google published a public repair manual to support customers and technicians. They also partnered to make genuine components available for this and other products.

iFixit awarded the watch a 9/10 repairability score and called it the most repairable smartwatch on the market. This external recognition reinforces the practical impact of the design decisions made throughout development.

The Pixel Watch 4 effort underscores that repairability in small devices is a systems challenge spanning architecture, components and materials. Integrating solutions yields devices that are better to keep, delivering longer lifecycles and a path for the industry to accelerate progress.
