Pixel Watch 5's Real Upgrade Isn't the Chip — It's the Strap
Google quietly swapped the material in its Active Band, and the change says more about the Pixel Watch 5 than any spec sheet.

Google's Pixel Watch 5 arrives with the same familiar silhouette and, largely, the same processor lineage the Pixel Watch line has used since 2023. But tucked into the spec sheet is a smaller, oddly specific update: a '2nd Gen Active Band,' now made from a different material entirely. It's the kind of detail easy to skim past — and exactly the kind that matters if you actually wear the thing.
Out with fluoroelastomer, in with HNBR
Every prior Pixel Watch Active Band was built from fluoroelastomer, the same category of rubber-like material Apple uses in its Sport Band. It's durable and holds up better than plain silicone, which tends to develop a sheen and pick up grime over time.
The Pixel Watch 5's second-generation band switches to hydrogenated nitrile-butadiene rubber, or HNBR. It's a tougher compound than what came before, and critically, it's PFAS-free — sidestepping the so-called 'forever chemicals' that fluoroelastomer bands, like many other consumer products, have relied on.
"The 2nd Gen Active Band swaps fluoroelastomer for PFAS-free HNBR rubber — a material change, not a redesign."
Same face, quietly better guts
Visually, nothing changes. The band looks identical to its predecessor, so this isn't a fashion refresh — it's a materials-engineering one. That mirrors how Google has approached the rest of the Pixel Watch 5's hardware this generation.
The chip story repeats itself
The Pixel Watch 5 reportedly still runs on the Snapdragon W5 Gen 2 platform, the same core silicon Google has used since the Pixel Watch 2, now marketed under an 'Accelerated' label that likely denotes tuning rather than a new chip. RAM reportedly climbs from 2GB to 3GB, and storage doubles to 64GB, while battery capacity ticks up slightly to 332 mAh on the 41mm model and 465 mAh on the 45mm — enough for a modest bump without changing Google's quoted battery-life figures of 30 and 40 hours with always-on display enabled.
None of this makes for a flashy keynote moment, but it fits a pattern: Google iterating on materials and efficiency rather than chasing headline silicon upgrades. Whether that's enough to justify the Pixel Watch 5 next to a similarly priced Apple Watch remains an open question, but the Active Band swap is a reminder that not every meaningful upgrade shows up in a benchmark.
Editorial Note
The research sources corroborate all major hardware specifications (processor, RAM, storage, battery) and confirm the existence of a 2nd Gen Active Band with updated materials. However, the article's specific claim that the new band material is HNBR and is PFAS-free cannot be verified from the provided research—the sources only confirm a material change without naming the replacement material or discussing PFAS content.

AI-assessed
Source 1 (9to5google) explicitly confirms: 'Like sporty bands seen on the Apple Watch, Google's "Active Band" for Pixel Watch has been made from a material called fluroelastomer.'
The research sources confirm a material change to the 2nd Gen Active Band but do not specify HNBR as the material name. Source 2 only states 'Google has reportedly updated the materials' without identifying what material.
Source 3 (9to5google) and Source 6 (memeburn) both confirm: 'It's a bold move for a watch running the same core processor it's used since the Pixel Watch 2 in 2023' and 'Under the hood, the Watch 5 runs the Snapdragon W5 Gen 2.'
Source 3 (9to5google) confirms: 'this leak confirms the 3 GB of RAM from 2 GB today, while storage is doubled to 64 GB.'
Source 3 (9to5google) confirms: 'The batteries see a very small increase to 332 mAh (from 325 mAh) on the 41mm... 465 mAh (from 455 mAh) on the 45mm model. That bump does not result in any changes to the quoted battery life of 30 hours with AOD on the smaller variant and 40 hours on the larger size.'
