The CMF Watch Pro 2 is a substantial redesign, not simply a refreshed version of the original. It trades the Watch Pro’s larger rectangular screen for a smaller round AMOLED display, and adds auto-brightness, interchangeable bezels, removable straps, multi-system GPS and a listed 120 sports modes. Choose it if those changes suit your priorities; the original remains worth considering if you prefer its rectangular screen or find it at a meaningfully lower local price.
What changed between the CMF Watch Pro and Watch Pro 2?
The biggest difference is the screen shape. The Watch Pro 2 also brings more documented customization and outdoor-workout features. The specifications below come from Nothing’s product and support pages; they are not independent test results.

| Charging dock | Uses the dock shared with Watch Pro 2. | Uses the same interchangeable dock as Watch Pro, according to Nothing Support. | Owners of the original can reuse its charging dock, according to Nothing. |
Is the Watch Pro 2’s smaller round screen better?
That depends on what you want from a watch face. The original’s 1.96-inch rectangular screen is larger on the diagonal, which may suit readers who prioritize a broad, rectangular display. The Watch Pro 2’s 1.32-inch round AMOLED is a different design, with higher listed pixel density and automatic brightness adjustment.

Do not treat the listed brightness numbers as a direct test of which screen is easier to see outdoors: Nothing gives 600 nits as typical brightness for the original and 620 nits as peak brightness for the Watch Pro 2. Those labels describe different measures.

For the original Watch Pro, Nothing’s support guidance describes IP68 in controlled-test terms and advises against deep water, heat and pressure exposure. Its cautions include pools, beaches, hot showers, saunas, scuba or deep/platform diving, and high-pressure washing; it also says liquid damage is not covered by warranty. For Watch Pro 2, Nothing lists IP68 and a 30-minute test at 1.5 metres. Neither statement establishes that either model is appropriate for every swimming or water activity; follow the cautions and warranty terms for your specific watch.
Which CMF watch should you buy?
Choose CMF Watch Pro 2 if
- You prefer a round AMOLED display with auto-brightness.
- You want the option to change the bezel or remove the strap.
- You value the listed multi-system GPS, 120 sports modes and five automatic-recognition activities.
- You have checked its current price and availability in your market.
Choose CMF Watch Pro if
- You prefer a larger rectangular screen.
- You find the original at a meaningfully better local price and do not need the newer model’s documented design and feature changes.
Upgrade from the original if
The round display, customization, documented GPS and workout features, or newer software integration matters enough to justify the price difference. The charging dock is reusable; do not assume your old straps or bezels will fit.
There is no universal winner without a local price check. Nothing’s EU storefront has shown a €69 price, but that is region-specific and should not be treated as a worldwide or necessarily current price. Compare the screen shape, customization, workout needs, accessory reuse, phone and app compatibility, and current local prices before deciding.
